resolver should be able to parse catalog files without needing to resolve external entities?

[Jack Bates]

I'm getting the following exception using the XML catalog resolver with
FOP,

[...]
DELEGATE_PUBLIC: -//W3C//DTD XHTML//EN
        file:/usr/share/xml/xhtml/schema/dtd/catalog.xml

I think it's the same issue reported here,
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=491091

- and here,
https://bugs.launchpad.net/ubuntu/+source/w3c-dtd-xhtml/+bug/400259

Is comment #4 correct?

"Arguably this is a bug in org.apache.xml.resolver, cf.
http://www.oasis-open.org/committees/download.php/14809/xml-catalogs.html#s.bootstrap
 - the resolver should be able to parse catalog files without needing to 
resolve external entities"
