Gary,

our XML Validator allows this test to pass because the test doesn't contain
a recognizable reference to %bad-pe;.

pe01.dtd:-

<!ENTITY % bad-pe SYSTEM "pe01.ent">
<!ELEMENT root EMPTY>
<!ATTLIST root
    something CDATA   "%bad-pe;"
    evil (doctor | scott) "doctor"
    >

What appears to be a reference to %bad-pe; isn't really a reference because
it appears inside a literal.  PEs are not recognised within literals except
for entity value literals.  In this case the 'something' attribute has a
literal default value of "%bad-pe;" - which is perfectly valid.
