All the parser does is determine if a document meets the criteria specified in 
an SGML Document Type Definition.  A generic parser would have trouble
producing
formatted output because SGML markup does not specify format.  You
could, however,
incorporate the parser in another program which would understand a specific DTD
and could produce a formatted document from the input.  The key thing to
remember
about SGML markup is that it is not like TROFF,  SGML only defines structure,
not appearance.
