The only SGML I'm aware of stands for Standard Generalized
Markup Language. I do not claim that this is the only facility
to use the SGML acronym.  SGML is an ISO standard (# 8879) and
is a generic language for marking up text.  It has virtually
no facilities for marking up graphics other than indicating
the location of a graphic element in a document and perhaps
the file name of the graphic.

SGML requires a parser and a formatting program to produce
text.  Troff or Tex are excellent for this kind of process.

SGML is independant of any hardware or formatting program.
Thus it can be used as a corporate standard for data archives
or Records Management.  It is also being adopted by numerous
typesetters.  This should make publishing a little more
competitive since editing need only go to the SGML stage and
no system-specific commands will be embedded in the document.

SGML is not a programming language.  There is no analogy
there.

ISO standards document:  Ref. No. ISO 8879-1986 (E).

There is also a publication of the American Association of
Publishers (AAP) dealing with their adoption of the standard.

Any kind of information can be designated, but the types of
information depend on the power of the formatter.  I don't see
why SGML can't be translated into a format for a technical
publishing system such as Interleaf.  We translate it into
troff and Ventura.
