DTD and fixed XML example for map file

[Doug Nebert]

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.
