That simply means there's still a bug in Xalan-J concerning SAX handling.
XLTC is probably sending and empty string instead of null to the
Element.setAttributeNS() method. The problem: SAX uses empty strings for
"no namespace", while the W3C DOM uses null. The XSLT implementations
have to convert between the two concepts.
SAXON had the same problem and older Xalan-J (non-XSLTC) versions, too.
Batik recently fixed something that avoids the error but that fix will
only be available after the next release. There's nothing FOP can do
here.
As a work-around, you can try to use the latest Batik Trunk (from
Subversion) which contains a fix. Better would be to alert the Xalan-J
people that they still have a problem in their XSLTC.
