Hi Eric,

You had recently (in Mandelieu) a question on citing Unicode. I looked
at charmod again and have the impression that the following answers your

[[The fact that both ISO/IEC 10646 and the Unicode Standard are evolving
(in synchrony) raises the issue of versioning: should a specification
refer to a specific version of the standard, or should it make a generic
reference, so that the normative reference is to the version current at
the time of reading the specification? In general the answer is both.

C063  [S]  A generic reference to the Unicode Standard MUST be made if
it is desired that characters allocated after a specification is
published are usable with that specification. A specific reference to
the Unicode Standard MAY be included to ensure that functionality
depending on a particular version is available and will not change over

An example would be the set of characters acceptable as Name characters
in XML 1.0 [XML 1.0], which is an enumerated list that parsers must
implement to validate names.]]

That is: your implementation has to choose whether it wants to go the
xml 1.0 or xml 1.1. way; in the later case, just cite Unicode as xml
1.1. does.

Regards, Felix.
