| I think that TM authors should have ability to specify typed data
| occurrences and use data types in queries even without any TMCL
| schema attached to topic map.

I agree with the second part, I think, but I'm unsure about the first.
Are you essentially proposing to extend the SAM with typed occurrence
values?
 
| TMCL can validate what is already in TM in terms of data types. It
| can help during authoring but I think that TMCL usage is not
| mandatory.

I agree it should not be mandatory, but it seems messy to have typing
both in TMCL and in TMQL. Maybe there is some way to resolve this
without duplicating anything, but that will require some thought, and
at the end of the day we may then have added a capability that is not
very interesting.

If it sounds as though I'm unconvinced but convincable, that's pretty
much correct. :)
