This seems reasonable and necessary.
I think we need to revisit the question, "what are Topic Maps for anyway?"
Where would topic maps fit in the storage and access of data objects?
We would need it, if we are getting into this business. Are we?
I really can't answer this.
The subject comes up (storage of data types) with engineers whenever I
discuss topic maps with then.

It would be a valuable extension, but whether it should be in the
requirements for the language is debatable, I think.
