2) How do namespaces and XLinks work together? For example, suppose I link to
the <Foo> element in another file.
a) If the <Foo> element is prefixed (that is, it is really <Bar:Foo>) does my
pointer need to know this?
b) When I get the <Foo> element back as a result of resolving the link, do I get
<Foo> or <Bar:Foo>? And if I get <Bar:Foo>, do I also get a namespace PI
telling me about the Bar prefix?
