Last night I spent ages puzzling over why I was failing test 0121 in
HTML4 and HTML5, but not XHTML1, and today it's come to me out of
nowhere.

<p about="http://example.org/">
  <span about="[]" property="dc:title">Test Case 0121</span>
  checks to make sure RDFa processors resolve the empty CURIE correctly.
  <p resource="[]">
    <span property="dc:contributor">Shane McCarron</span>
    contributed to this test.
  </p>
</p>

In HTML, paragraphs cannot be nested. (In XHTML1 this is invalid too,
but well-formed.) Thus, in parsing, the opening of the second paragraph
automatically closes the first paragraph. Thus the above parses as if it
were:

<p about="http://example.org/">
  <span about="[]" property="dc:title">Test Case 0121</span>
  checks to make sure RDFa processors resolve the empty CURIE correctly.
</p>
<p resource="[]">
  <span property="dc:contributor">Shane McCarron</span>
  contributed to this test.
</p>

So the subject of the second triple is the implicit about="" on the
<body> element. So, as far as HTML parsing is concerned, my parser is
right and the test case's SPARQL result is wrong.

Suggestion: replace the second <p> element with <b> or something.

My suggestion to drop test case 0113 from the HTML test suites still
stands too.

As I believe these two test cases in the HTML test suites are erroneous,
I won't be changing my parser to "pass" them. Other than that,
RDF::RDFa::Parser is now passing all the HTML4, HTML5 and XHTML1 tests.
