why still matching on VisualObject rather than use the much simpler (and
working) suggestion of matching on
VisualObject[@xsi:type='CBarCode']/FontFace" ?

No you don't need to declare that namespace (you can call the function
as matches() rather than fn:matches()) but it is an XPath 2 function, so
only usable in XSLT 2, and you stated you need XSLT 1.

You can declare any number of namespaces on an element, but that would
not help you in this case.
