Tests invalid p:document with dtd-validate='true'.
Test ab-p-document015.xml is expected to fail with one of the following error codes: err:XD0011
or err:XD0023
.
<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-invalid-doc-dtd-external.xml" parameters="map{'dtd-validate': true()}"/>
</p:with-input>
</p:identity>
</p:declare-step>
