What a funny example to pick--to demonstrate <itemset/> in FormFaces we
made a page doing *exactly* this. <itemset/> is the element you will
want to use. <itemset/> lets the options for a select control be
populated dynamically with the choices being taken from the instance

I've attached our example page, which lets you choose the type of
vehicle, the make, and the model.

Incidentally, the @nodesets for the three <itemset/>s are fairly
complex. We found that they were much simpler to write once we added
support for the current() function from XSLT. If your processor of
choice supports that function, you can significantly shorten those
binding XPaths.
