Re: [ubl-cmsc] XSD Derivation

["Eve L. Maler" <eve.maler@sun.com>]

Some kinds of derivation allowed in the XSD spec (restriction, substitution 
groups) are not universally implemented.  If we left these out of 
consideration, and the question were just "Should XSD complex type 
extension be used...?", I could see an argument for doing that in an 
XSD-native way rather than performing a schema-to-schema 
transformation.  But there may be costs to treating this kind of context 
rule differently from the others.  In short, I'm with Eduardo on this one. :-)
