Using xmllint from libxml2-2.7.3 as follows results in an error.

-----BEGIN test.xml-----
<?xml version="1.0" encoding="UTF-8"?>
<test xmlns="http://example.org/xmllint-xsd-test-n-roeser-1a#"

This looks very much like the problem described in <URL:http://xsd.stylusstudio.com/2006May/post04004.htm> to me.




By the way: options for version 2.7.2 and 2.7.3 are missing in GNOME Bugzilla for product libxml2. Please add them.

Thanks.
