Re: [sdo] Re: ISSUE 173: Is Type name an NCName?

Hi Blaise,

The rules you extracted are from the XML 1.0 5th edition. These were changed from the 4th edition to align with the more permissive rules of XML 1.1 names.

I haven't seen much adoption XML 1.0 5th edition, particularly in the Java space. Someone using an NCName which was not allowed by XML 1.0 4th edition is unlikely to have much success with existing software. Did you really just intend to point to the XML Schema definition of NCName [1]? This still goes by the definition of NCName [2] in the original Namespaces in XML Recommendation.

Thanks.
