RE: [xsl] Unique values in tags

XML Schema has an element called xsd:unique that can be used for this
purpose. Google for it; there's a few discussions about its usage (with good
examples) available on the web.

Subject: [xsl] Unique values in tags

Hello all:

 After 3 months away from xsl development, i'm gladly returned to it, and to
this excelent, one-of-a-kind, superb list.

 I have a question and i don't know if the answer is XSL or Schema, but here
it goes.

 I have a XML file with an associated Schema. That XML file will be edited
on some XML editors (Oxygen and/or Exchanger) and i have to force the user
to only insert unique values on a certain tag, something like a key.

 So the question is: Is it possible to define in the Schema that certain tag
has unique values?

 If not, is it possible using similar aproaches like DTD or RelaxNG?

 if not, is it possible using XSL/XSLT?

 Thanks a lot.

 One more question, is it ok to post Schema related questions on this list?
If not, can someone point me to one?

 Thanks again.
