[Announce] Free RELAX-NG resource for editing/validating UBL 2.0 and draft UBL 2.1 schemas

I'm pleased to announce another free UBL-related resource is 
available on Crane's web site:  RELAX-NG compact syntax schemas for 
editing and validating instances of UBL 2.0 and draft UBL 2.1 schemas:

     http://www.CraneSoftwrights.com/resources/ubl/#ublrnc

This uses James Clark's Trang utility plus some massaging:  the 
presence of the optional UBLVersionID attribute is obliged to have 
the value "2.0" or "2.1", which then in turn ensures the remainder of 
the instance conforms to that version of the document model.  The 
documentation illustrates a simple example of this.  Your editing 
environment points to a single schema and all versions of that 
document type are automatically accommodated accordingly.

I created this resource because I use James Clark's nXML 
RELAX-NG-schema-aware major mode editing environment for the infamous 
Emacs editor.  These should work just as well in any 
RELAX-NG-schema-aware environment such as oXygen.

I will try to keep this environment up to date with all releases by 
the UBL SGTG of draft UBL 2.1 schemas.

Please let me know off list if you have any questions or suggestions.

Thanks!
