RE: XP Service URIs

The first is called an <xp module> which uses XML NS to identify what it
is and what parameters it carries within an <xp message>.

The second is called the <ultimate xp receiver> which indicates where
the message is going.

It is possible to have multiple <xp modules> in the same messsage using the
*same* XML NS identifier. An example is some signature module which is used
multiple times in the same <xp message>. If this is the case, then the module
may need to have a mechanism for separating the two "instances", for example
in order to disambiguate which one failed in the case of an <xp fault>.
