Why don't you just make the javax.faces.DEFAULT_SUFFIX .xml? I suppose you
want to have a gradual migration. In that case, why can't JSF support
multiple extensions, searched in priority order. I guess that is something
an impl could provide (since migrations are something that you might look to
a vendor to help you solve). The spec should assume you are using a single
type (I guess).
