Some comments on the July 17 XInclude draft

In the second paragraph in section 3, it says external entities with
multiple top-level elements cannot be included from. Why not? It seems
to be that such inclusion can be useful.

About the issue XInclude-31-which-namespace. It seems like a good idea
to use the "xml" namespace, however an inclusion instruction like

<someelement xml:href="foo.xml"/>

looks a bit strange and doesn't suggest that it's an inclusion.
However, if you revert to the element syntax, then

<xml:include href="foo.xml"/>

would be very clear.
