Tests p:with-input with missing @port on atomic step: XS0065 is raised because there is no primary input port.
Test ab-with-input-002.xml is expected to fail with error code err:XS0065.
<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:load href="irrelevant">
      <p:with-input/>
   </p:load>
</p:declare-step>
Added href attribute so that err:XS0018 is not an equally valid error.
Fix namespace declarations
Creating new tests, extending rng and corrected xproc's test
