Actually, JAXP 1.1 is using {http://www.foo.com/}doc

Yes.

I suspect most processors keep the original prefix with the
element/attribute on the tree, event though the spec says that they don't
need to. The spec is written on the basis that the prefix can be recovered
by examining the namespace nodes. (Actually, the spec for the name()
function in XPath 1.0 leaves a great deal to the imagination, which becomes
a problem when applying name() to nodes in result tree fragments at XSLT
1.1).
