You'll lose the entity-boundary information in this case.  What you'd
get back is

  internalEntityDecl("foo", true, "foo CDATA #REQUIRED");
  attributeDecl("bar", "foo", "CDATA", null, ATTRIBUTE_REQUIRED, refs);

You're right, but I think that we're taking this too far for the SAX
core.  SAX2 is specifically set up so that people can define new
handler types, so it is possible to come up with something that
provides this level of reporting, but it will have to be outside of
the SAX core.

All the best,
