RE: using node-set() extension function across vendors

The official answer is using function-available(). 

But you could try a solution that uses entities: replace the
xx:node-set(expr) by &xx-node-set;(expr), and use EntityResolvers,
catalogs, etc, to expand the xx-node-set entity reference differently on
different occasions.
