Just one relationship is needed for something like size. There is, of
course, nothing to prevent multiple relationships between an abstract
object and a datatype value.

Yes, but I don't see a use of this in your document to relate an abstract
object to a datatype value. The examples seem to indicate that the
relationship to the literal is the one that is specified and the
relationship to the datatype value is inferred from it.
A fully-worked out set of examples would be illustrative. They would be
helpful as we wrestle with a better version of the datatype spec that might
relax some of the restrictions in the current proposal.
