Yes, that would definitely be nice, but I think on the entailment
regimes telecon we agreed that an exact specification could also be
left open for now. Systems can add something to their service
descriptions indication what profile they support, but it is not
necessarily standardised. Much in the same way as systems already
support aggregates, but only now the most popular and established
aggregaton functions are standardised. If Greg wants to add something
in that direction, I am happy to work on that with him.
