It lets people put XQuery documents on public Web servers that may
not be configured correctly.  But it's not clear that this is the
right approach.  Thank you for the comment.

In the MIME context that's true -- so far XQueryX has mostly (entirely?)
been used offline, where there's no charset parameter.

Thanks for spotting this.

We expect to add to it later.  Right now the specifications are new
enough (in terms of Process) that security implications have not
all been explored.  I'd welcome help in this area.  What sort of
additional text did you expect in this section?

It's non-normative within the context of the XQueryX specification:
an implementation does not need to support anything here in order
to claim conformance.  If you do support application/xquery+xml though,
this is how you must do it.

I hope that's clearer.  It's been difficult to see the balance between
making th documents stand alone and making them also work as part of a
larger specification.
