I only have one validating XML parser on this machine IBMs
XML4J:-
doc.dtd
<!ELEMENT foo (#PCDATA)>
<![IGNORE[
<!ATTLIST foo bar CDATA #REQUIRED>
]]>
a.xml
<?xml version="1.0"?>
<!DOCTYPE foo [
<!ENTITY % dtd SYSTEM "doc.dtd">
%dtd;
]>
<foo></foo>
b.xml
<?xml version="1.0"?>
<!DOCTYPE foo SYSTEM "doc.dtd">
<foo></foo>
b.xml validates. a.xml fails reporting:-
Error: Conditional section only allowed in external subset. (2,3)
