PrefixResolver.getURI()

[Suzanne Dirkers]

Dear Folks,

          All I see in the documentation about what this is supposed to be
is the 'base URI for the Resolver'. huh?   What exactly does this mean? Is
this supposed to be the first namespaceURI on the document element, or
what?   Is there an assumption that URIs are built on top of each other in
some fashion that I have never heard of?  How are we generally supposed to
get this?
