RE: [xml-dev] Schematron: Categories of Usage?

Hi Roger

Universal Business Language is promoting use for enumeration checking
due to limitations in that area on extensibility by derivation in W3C XML
Schema (inability to extend an enumeration using substitution groups or
redefine).
http://docs.oasis-open.org/ubl/os-UBL-2.0/val/defaultCodeList.xsl
It covers restriction of an enumeration list too of course. The enumerations
are kept separate from the XSD schema files and validated using Schematron.

All the best
