49  *  Program to manipulate SGML instances.
50  *
51  * Originally coded for OSF DTD tables, now recoded (fld 3/27/95)
52  * for CALS-type tables (fragment taken from the DocBook DTD).  Then,
53  * *really* upgraded to CALS tables by FLD on 5/28/96.
54  *
55  *  This module is for handling table markup, printing TeX or tbl
56  *  (tbl) markup to the output stream.  Also, table markup checking is
57  *  done here.  Yes, this depends on the DTD, but it makes translation
58  *  specs much cleaner (and makes some things possible).
59  *
60  *  Incomplete / not implemented / limitations / notes:
61  *	vertical alignment (valign attr)
62  *	vertical spanning
63  *	row separators are for the whole line, not per cell (the prog looks
64  *		at rowsep for the 1st cell and applies it to the whole row)
65  *	trusts that units in colwidths are acceptable to LaTeX and tbl
66  *	"s" is an acceptable shorthand for "span" in model attributes
67  *
68  *  A note on use of OutputString():  Strings with backslashes (\) need lots
69  *  of backslashes.  You have to escape them for the C compiler, and escape
70  *  them again for OutputString() itself.
