As I understand it, XML core allows several different parser behaviors 
here (ranging from "report a well-formedness error" to "load the DTD and 
expand entities using it" to "use a local catalog" to "just shows the 
unexpanded entities as text").  I could be wrong in this understanding, 
of course; please correct me if I am.

If I understand correctly, browsers have by and large chosen a 
particular behavior: using a local catalog for particular DTDs.  The 
suggestion is to define that those particular DTDs should use a specific 
local catalog and what that local catalog is.

Since the DTDs involved are the various XHTML DTDs, it seems that this 
group might be the one tasked with such definition.

Agreed; this discussion isn't about XHTML5 per se.

In the area of "html" (whatever that might mean), this does in fact seem 
like the job of this working group, fundamentally.
