Subject: | XML::LibXML::Dtd->new() returns undef and doesn't say why on invalid DTD |
See:
https://svn.berlios.de/svnroot/repos/web-cpan/XML-Grammar-ProductsSyndication/trunk/xslt/
if you run Test.t using "perl" (or "prove") you'll see that it fails.
It attempts to load a DTD based on the modularised-XHTML DTD, and
fails. The DTD has a bug, but it just returns undef and doesn't report
where the bug occurs and what it is.
