Found a neat validator/DTD generator at:
http://www.pault.com/Xmltube/dtdgen.html
Attached are a validated XML instance file and the DTD generated from
it. Note that DTD elements are presented in alphabetic order rather than
in logical order. Read the results carefully!
However, when an item shows up as a part of another item (e.g.) WEB has
HEADER and TEMPLATE, the parsing expected order of these subfields is
rigorous in XML 1.0. You can't, say, legally switch the order of
occurence of TEMPLATE and HEADER in a picky parser. I imagine future
implementations based on XML-Schema will relax the element order and
case sensitivity requirements of the current generation.
