No. Catalogs can only be used by registering an EntityResolver with
the XMLReader and a URIResolver with the Transformer. FOP's CLI code
currently just does not do this.

Users do not like to have to know the name of such an obscure
property. Configuring the class path is already a lot to ask from
someone not interested in Java per se.
