generate-id.xml about qt3tests

Sorry, I don't see the difference between "must consist of ASCII alphanumeric characters and must start with an alphabetic character" and "must match the regular expression ^[A-Za-z][A-Za-z0-9]*$". Perhaps it's the bit about XML names that's confusing? Every valid result of generate-id() is a valid NCName, but it's not intended that every valid NCName is a valid result of generate-id().

The rule dates from XSLT 1.0 and I think its intent was that the result should be a valid name in many different contexts, e.g. SQL or Java or Fortran as well as just XML.

The phrase "the string is an XML Name" is not intended to be read as "the set of strings is the same as the set of XML Names".

Exactly, that was the sentence that led to my confusion. I was surprised indeed that the constraints on ids returned by this function are stricter than general constraints on XML ids (which only require an id to be a valid NCName).

Thanks for the clarification and the reasoning how this constraint came into existence.
