It's the namespace:: axis support issue in Firefox. The known workaround 
is to add, preferably at the document element, a dummy attribute such as 
mods:dummy="dummy".

Checking empty values vs. missing nodes is, of course, not exactly the 
same, depending on the context but missing nodes produce empty values in 
XPath 1.0!
