Let FooML be a XML format with legacy linking mechanisms that allows use
of arbitrary foreign attributes such that a conflict between XLink 1.1
linking and the legacy linking could arise. I want to make a FooML +
XLink 1.1 implementation. No errors, same problem. Also note that XHTML
M12N allows to make a XHTML 1.1 + XLink 1.1 document type.
