justify or remove aliases: base-uri, resolve-uri

The xproc spec makes aliases of fn:base-uri and fn:resolve-uri:

"The semantics of this function are the same as the semantics of the
XPath 2.0 fn:base-uri() function.

Function: string p:base-uri()"

likewise p:resolve-uri


We shouldn't do that for various reasons; see...
  http://www.w3.org/TR/webarch/#avoid-uri-aliases

Please add rationale for the aliases or take them out.

I'm presuming qnames such as p:base-uri are mapped
to full URIs somewhere, though I can't find the mapping
in a quick skim of the spec.
