Good point ... but I think I like Stephen's later suggestion of what to use 
for indicating the cardinality.

Indeed I used Python myself to go from the "-xpath.xml" file to each of the 
HTML, text and XML formats ... SAX is all that is needed for this kind of 
stream processing ... and the multi-megabyte XPath files for the complete 
UBL package bogged down every XSLT processor I tried.

So noted.

I'll spell it all out ... just wanted to know if one letter was too cryptic 
when I included as a comment in the file the detail of the vocabulary.

Nope ... no reason ... will change to ".html"

I like Steve's observation that by keeping it ".xml" then tools will know 
how to open it.  I hadn't considered that.

Good point!

Rather than the Kleene operators, I'll go with the "0..1" pattern ... 
especially noting that we have a "1..7" in one of the fields and a 
single-character token can't represent all possible combinations uniquely.

>3. How far is this from RelaxNG? :)

Yes, RELAX-NG does use Kleene operators.  (aside: did you know RELAX is an 
abbreviation for "REgular LAnguage for XML"?

Thanks Micah!
