comments on rdf:text solicited

Dear all,

find at
  http://www.w3.org/2007/OWL/wiki/InternationalizedStringSpec

the prefinal version of the rdf:text datatype, now with 
Xquery/Xpath-style built-in functions added.

I have added a rudimentary set of built-ins.
The most essential ones are those from seciton 4.1. to assemble and 
disassemble rdf:text.

The others (sections 4.2, 4.3) are mostly syntactic sugar, which is 
shown by for most of them also a declared XQuery function being given to 
emulate them. Still, I think these are important enough to be kept in 
the spec.

An exception is  fn:matches-language-range which exposes language range 
matching as defined in RFC 4647 (part of BCP-47) as a built-in function.

I think thee cover the most essential functions needed for rdf:text.

The RIF versions of these will be defined in an update of DTB, along 
with examples how to emulate (min-/max-length, etc.) facets using these 
functions in RIF rules.

Please comment until mid next week latest, since the OWL group really 
needs this document to be finished.

Axel
