RE: the doc('') function

I think that the empty URI in doc() should be resolved against the base URI of the p:input element, which, in this case, should return the pipeline document itself. The XPath expression in p:input is evaluated using the processor context, the context node is undefined, and the base URI is (see 2.6.2.1) is “the base URI of the element on which the expression occurs.”

That is also consistent with:

<p:declare-step xmlns:p="http://www.w3.org/ns/xproc" version="1.0">
  <p:output port="result"/>
  <p:identity>
    <p:input port="source">
      <p:document href=""/>
    </p:input>
  </p:identity>
</p:declare-step>
