Go back and look closer at the test classification:  "error", meaning
there's something strange about it that parsers are NOT required to
report.  (Just like non-deterministic content models ...)

In this case, the test predates resolution of the PE-in-attributes issues
from the W3C process, and was intended to address text in the XML
spec referenced by that test metadata (in section 2.8).  Likely a better
way to test that requirement would be to put the PE  reference into
a conditional section that's not expanded.
