/*
 * This module contains the programs which construct the syntactic
 * representation of the WML input. All the routines are called as
 * actions of the grammar productions.
 *
 * Since WML is so simple, no stack frame technology is used. Instead,
 * context is maintained by global pointers and vectors which contain
 * the intermediate results of parsing a statement. At most, these
 * contain an object being constructed (for instance a class descriptor)
 * and a subobject (for instance a resource reference in a class).
 *
 * Results are communicated back using the global error count
 * wml_err_count, and the ordered handle list wml_synobj_ptr.
