Starting to work through the TMCL draft but while trying to track down 
one possible issue I stumbled in an issue with regular expressions.

We say:

> A string /s/ matches a regular expression /r/ if the string is a 
> member of the set of strings |L(r)| denoted by /r/ as defined in /[XML 
> Schema-2 <http://www.isotopicmaps.org/tmcl/tmcl.html#XSD2>]/. 
Err, does that mean that conforming TMCL processors will recognize 
regular expressions defined using the regex syntax defined inAppendix F 
of XML Schema Part 2?

The reference and the requirement to conform to that syntax seems a big 

Please add an issue to specify the regular expression syntax as defined 
by XML Schema Part 2 and appropriate conformance requirements.

Hope everyone is having a great day!
