First, application/xhtml+xml is not written for browsers. Browsers may
be the biggest implementors, but they're not the only implementor.

Second, what you're discussing seems to be something that's general to
all XML parsers, not just browsers. As such, it would be better
defined as part of XML core, rather than an end case like HTML5. Or is
there something unique that the browsers do that falls outside of
normal XML parsing?

Besides, the point is moot: XHTML5 does not have a DTD, only the five
predefined works with the XHTML.

The job of this working group is not to normalize all of the browser
quirks and differences. Don't you agree?

What exactly would you expect the EntityResolver to do with XHTML that
it wouldn't do with other flavors of XML?
