@htmlinclude pkg-marker-core.html Abstract class for references to species in reactions.
 *
 * As mentioned in the description of Reaction, every species that enters
 * into a given reaction must appear in that reaction's lists of reactants,
 * products and/or modifiers.  In an SBML model, all species that may
 * participate in any reaction are listed in the 'listOfSpecies' element of
 * the top-level Model object.  Lists of products, reactants and modifiers
 * in Reaction objects do not introduce new species, but rather, they refer
 * back to those listed in the model's top-level 'listOfSpecies'.  For
 * reactants and products, the connection is made using SpeciesReference
 * objects; for modifiers, it is made using ModifierSpeciesReference
 * objects.  SimpleSpeciesReference is an abstract type that serves as the
 * parent class of both SpeciesReference and ModifierSpeciesReference.  It
 * is used simply to hold the attributes and elements that are common to
 * the latter two structures.
 *
 * The SimpleSpeciesReference structure has a mandatory attribute,
 * 'species', which must be a text string conforming to the identifer
 * syntax permitted in %SBML.  This attribute is inherited by the
 * SpeciesReference and ModifierSpeciesReference subclasses derived from
 * SimpleSpeciesReference.  The value of the 'species' attribute must be
 * the identifier of a species defined in the enclosing Model.  The species
 * is thereby declared as participating in the reaction being defined.  The
 * precise role of that species as a reactant, product, or modifier in the
 * reaction is determined by the subclass of SimpleSpeciesReference (i.e.,
 * either SpeciesReference or ModifierSpeciesReference) in which the
 * identifier appears.
 *
 * SimpleSpeciesReference also contains an optional attribute, 'id',
 * allowing instances to be referenced from other structures.  No SBML
 * structures currently do this; however, such structures are anticipated
 * in future SBML Levels.

/**
   * Returns the value of the 'id' attribute of this SimpleSpeciesReference.
   *
   * @note Because of the inconsistent behavior of this function with
   * respect to assignments and rules, it is now recommended to
   * use the getIdAttribute() function instead.
   *
   *
 *
 * The identifier given by an object's 'id' attribute value
 * is used to identify the object within the SBML model definition.
 * Other objects can refer to the component using this identifier.  The
 * data type of 'id' is always <code>SId</code> or a type derived
 * from that, such as <code>UnitSId</code>, depending on the object in
 * question.  All data types are defined as follows:
 * <pre style='margin-left: 2em; border: none; font-weight: bold; color: black'>
 *   letter ::= 'a'..'z','A'..'Z'
 *   digit  ::= '0'..'9'
 *   idChar ::= letter | digit | '_'
 *   SId    ::= ( letter | '_' ) idChar*
 * </pre>
 * The characters <code>(</code> and <code>)</code> are used for grouping,
 * the character <code>*</code> 'zero or more times', and the character
 * <code>|</code> indicates logical 'or'.  The equality of SBML identifiers
 * is determined by an exact character sequence match; i.e., comparisons must
 * be performed in a case-sensitive manner.  This applies to all uses of
 * <code>SId</code>, <code>SIdRef</code>, and derived types.
 *
 * Users need to be aware of some important API issues that are the result of
 * the history of SBML and libSBML.  Prior to SBML Level&nbsp;3
 * Version&nbsp;2, SBML defined 'id' and 'name' attributes on only a subset
 * of SBML objects.  To simplify the work of programmers, libSBML's API
 * provided get, set, check, and unset on the SBase object class itself
 * instead of on individual subobject classes. This made the
 * get/set/etc. methods uniformly available on all objects in the libSBML
 * API.  LibSBML simply returned empty strings or otherwise did not act when
 * the methods were applied to SBML objects that were not defined by the SBML
 * specification to have 'id' or 'name' attributes.  Additional complications
 * arose with the rule and assignment objects: InitialAssignment,
 * EventAssignment, AssignmentRule, and RateRule.  In early versions of SBML,
 * the rule object hierarchy was different, and in addition, then as now,
 * they possess different attributes: 'variable' (for the rules and event
 * assignments), 'symbol' (for initial assignments), or neither (for
 * algebraic rules).  Prior to SBML Level&nbsp;3 Version&nbsp;2, getId()
 * would always return an empty string, and isSetId() would always return @c
 * false for objects of these classes.
 *
 * With the addition of 'id' and 'name' attributes on SBase in Level&nbsp;3
 * Version&nbsp;2, it became necessary to introduce a new way to interact
 * with the attributes more consistently in libSBML to avoid breaking
 * backward compatibility in the behavior of the original 'id' methods.  For
 * this reason, libSBML provides four functions (getIdAttribute(),
 * setIdAttribute(@if java String@endif), isSetIdAttribute(), and
 * unsetIdAttribute()) that always act on the actual 'id' attribute inherited
 * from SBase, regardless of the object's type.  <strong>These new methods
 * should be used instead of the older getId()/setId()/etc. methods</strong>
 * unless the old behavior is somehow necessary.  Regardless of the Level and
 * Version of the SBML, these functions allow client applications to use more
 * generalized code in some situations (for instance, when manipulating
 * objects that are all known to have identifiers).  If the object in
 * question does not posess an 'id' attribute according to the SBML
 * specification for the Level and Version in use, libSBML will not allow the
 * identifier to be set, nor will it read or write 'id' attributes for those
 * objects.

/**
   * Returns the value of the 'name' attribute of this SimpleSpeciesReference object.
   *
   *
 *
 *
 * In SBML Level&nbsp;3 Version&nbsp;2, the 'id' and 'name' attributes were
 * moved to SBase directly, instead of being defined individually for many
 * (but not all) objects.  LibSBML has for a long time provided functions
 * defined on SBase itself to get, set, and unset those attributes, which
 * would fail or otherwise return empty strings if executed on any object
 * for which those attributes were not defined.  Now that all SBase objects
 * define those attributes, those functions now succeed for any object with
 * the appropriate level and version.
 *
 * The 'name' attribute is
 * optional and is not intended to be used for cross-referencing purposes
 * within a model.  Its purpose instead is to provide a human-readable
 * label for the component.  The data type of 'name' is the type
 * <code>string</code> defined in XML Schema.  SBML imposes no
 * restrictions as to the content of 'name' attributes beyond those
 * restrictions defined by the <code>string</code> type in XML Schema.
 *
 * The recommended practice for handling 'name' is as follows.  If a
 * software tool has the capability for displaying the content of 'name'
 * attributes, it should display this content to the user as a
 * component's label instead of the component's 'id'.  If the user
 * interface does not have this capability (e.g., because it cannot
 * display or use special characters in symbol names), or if the 'name'
 * attribute is missing on a given component, then the user interface
 * should display the value of the 'id' attribute instead.  (Script
 * language interpreters are especially likely to display 'id' instead of
 * 'name'.)
 *
 * As a consequence of the above, authors of systems that automatically
 * generate the values of 'id' attributes should be aware some systems
 * may display the 'id''s to the user.  Authors therefore may wish to
 * take some care to have their software create 'id' values that are: (a)
 * reasonably easy for humans to type and read; and (b) likely to be
 * meaningful, for example by making the 'id' attribute be an abbreviated
 * form of the name attribute value.
 *
 * An additional point worth mentioning is although there are
 * restrictions on the uniqueness of 'id' values, there are no
 * restrictions on the uniqueness of 'name' values in a model.  This
 * allows software applications leeway in assigning component identifiers.
 *
 * Regardless of the level and version of the SBML, these functions allow
 * client applications to use more generalized code in some situations
 * (for instance, when manipulating objects that are all known to have
 * names).  If the object in question does not posess a 'name' attribute

/**
   * Unsets the value of the 'name' attribute of this SimpleSpeciesReference.
   *
   *
 *
 *
 * In SBML Level&nbsp;3 Version&nbsp;2, the 'id' and 'name' attributes were
 * moved to SBase directly, instead of being defined individually for many
 * (but not all) objects.  LibSBML has for a long time provided functions
 * defined on SBase itself to get, set, and unset those attributes, which
 * would fail or otherwise return empty strings if executed on any object
 * for which those attributes were not defined.  Now that all SBase objects
 * define those attributes, those functions now succeed for any object with
 * the appropriate level and version.
 *
 * The 'name' attribute is
 * optional and is not intended to be used for cross-referencing purposes
 * within a model.  Its purpose instead is to provide a human-readable
 * label for the component.  The data type of 'name' is the type
 * <code>string</code> defined in XML Schema.  SBML imposes no
 * restrictions as to the content of 'name' attributes beyond those
 * restrictions defined by the <code>string</code> type in XML Schema.
 *
 * The recommended practice for handling 'name' is as follows.  If a
 * software tool has the capability for displaying the content of 'name'
 * attributes, it should display this content to the user as a
 * component's label instead of the component's 'id'.  If the user
 * interface does not have this capability (e.g., because it cannot
 * display or use special characters in symbol names), or if the 'name'
 * attribute is missing on a given component, then the user interface
 * should display the value of the 'id' attribute instead.  (Script
 * language interpreters are especially likely to display 'id' instead of
 * 'name'.)
 *
 * As a consequence of the above, authors of systems that automatically
 * generate the values of 'id' attributes should be aware some systems
 * may display the 'id''s to the user.  Authors therefore may wish to
 * take some care to have their software create 'id' values that are: (a)
 * reasonably easy for humans to type and read; and (b) likely to be
 * meaningful, for example by making the 'id' attribute be an abbreviated
 * form of the name attribute value.
 *
 * An additional point worth mentioning is although there are
 * restrictions on the uniqueness of 'id' values, there are no
 * restrictions on the uniqueness of 'name' values in a model.  This
 * allows software applications leeway in assigning component identifiers.
 *
 * Regardless of the level and version of the SBML, these functions allow
 * client applications to use more generalized code in some situations
 * (for instance, when manipulating objects that are all known to have
 * names).  If the object in question does not posess a 'name' attribute
 * according to the SBML specification for the Level and Version in use,
 * libSBML will not allow the name to be set, nor will it read or
 * write 'name' attributes for those objects.

 * introduced for attribute values that refer to <code>SId</code> values; in

 * explicitly name the data type.
