Link to the nearest anchor in the relevant section of the page or, at 
the very least, just to the page itself.  It's not an ideal solution, 
but there's not much else that can be done.

That looks like an attempt to redefine how fragment identifiers work for 
HTML and XML documents, which is out of scope for this spec.

I'm confused.  The subject of this thread you started is "Should ID be 
required for <DFN>?", yet now when a suggestion requires the use of an 
ID, you point out holes in it by trying to show that the required use of 
an ID has problems.
