I suggest using a different word for this thing. Quoting SGML ISO 8879-1986 Section 4.102: Document Type: A class of documents having similar characteristics; for example, journal, article, technical manual, or memo. Quoting SGML ISO 8879-1986 Section 4.105: Document Type Definition: Rules, determined by an application, that apply SGML to the markup of documents of a particular type. ... This definition of DTD doesn't confer that Document Type is restricted to only SGML, just that the DTD is the SGML way of looking at a Document Type (i.e. a class of documents). >>Questions for the model... >> >> a.

Going back to the roots of document markup, I think the term is very appropriate. ................. Ken -- Upcoming: 3-days XSLT/XPath and/or 2-days XSLFO - Feb 18-22, 2002 G.
