Tests that a p:document with an @href to a not well-formed document
      raises err:XD0049.
Test ab-p-document010.xml is expected to fail with error code err:XD0049.
<p:declare-step xmlns:err="http://www.w3.org/ns/xproc-error" xmlns:p="http://www.w3.org/ns/xproc" version="3.0">
   <p:output port="result">
   <p:identity>
      <p:with-input>
         <p:document href="../documents/ab-not-wellformed.xml">
      </p:with-input>
   </p:identity>
</p:declare-step>
Correct error code, err:XD0049 is expected.
Fix namespace declarations
Some new tests.
