#156 XPath docdef BaseNames: inexplicable xlink ns prefix error

[Evan Lenz]

When trying to add an XPath docdef that uses
ftss:BaseNames, I get the following traceback.
Interestingly enough, if only updating the docdef (rather
than creating it), the operation succeeds. So my
workaround currently is to comment out the BaseNames
element, create the docdef, uncomment BaseNames,
and update the docdef.
