I think that it is a transformer because it actually transforms elements in
its namespace to their bean representation. And you can use any generator to
create the input for the transformer, e.g.: an XSP page (not only a static
xml file) can be used to generate dynamic markup including castor
transformer elements.

Of course, it can be also a generator, but in that case you would support
all possible sources of input markup.

Depends on the purpose of the component.
