Says the schema doc. I > imply from that it must be ruled out in the schema doc. Well, firstly, NMTOKEN isn't a set, subset, or list, it's a string. Secondly, a normative reference from the Schema specification to the XML specification has the same force as spelling out the rules in the schema specification. Thirdly, it is in fact spelt out in the schema specification: the definition of the xs:NMTOKEN data type in the schema for schemas has <xs:pattern value="\c+" id="NMTOKEN.pattern">. (Search in XML Schema Part 2 for 'simpleType name="NMTOKEN"' to find it). > > > for minor comments like these, the best approach is to enter a bug > report > > - one per problem - in the bugzilla database. > > Where is the bugzilla database to do this? > http://www.w3.org/Bugs/Public/query.cgi Michael Kay http://www.saxonica.com/
