I agree that the are separate issues but clearly they are related and
influence each other. A "subset XML" that removes all the existing
mechanism to declare IDs has restricted the options down to

a) Use XML Schema if you want IDs, otherwise there are none
b) A new, in-band mechanism will provide IDs.

Yes it clearly applies to XML in general - its very important that the
subset XML is a true subset and no a forked, subset-plus.

But its also true that the need for a ID solution becomes more acute
when a subsetted XML (that has no internal or external DTD subset) is
