Controlled values, @collection-type enumerations and glossaries

[Deborah_Pickett@moldflow.com]

Hi,

I'm sure Eliot and Erik know the answer
to this, but I have a followup question that I'd like to discuss with everyone.

The @collection-type attribute is an
enumeration in 1.1 (with possibilities unordered, sequence, family, choice).
 Will DITA 1.2 relax this so that specializers can add new collection-type
values?  (I am assuming from #12022 and #12031 that the answer is
"yes", but I want to confirm that.)

I am thinking, in particular, of a collection-type
on the parent topicref of a set of glossentry topics, which would indicate
to implementations that the descendants form a glossary set.  Implementations
could use that indication to (say) sort the entries, concatenate entries
that have the same title, construct a mini-TOC page, etc.  Of course,
such processing is none of DITA's business, but there is a real need for
this kind of thing (see a discussion this week on dita-users), and it seems
to me that @collection-type is the right place for such a thing.
