Castor transformer or generator?

[Michael Homeijer <M....@devote.nl>]

Does anybody know why the castor transformer was actually built as a
transformer while it probably fits more in Cocoon as a generator?
Would the only difference be that the following two lines:
<map:generate src="test.xml"/>
<map:transform type="castor"/> 

 are written as:
<map:generate type="castor" src="test.xml"/>

Are there any other things to consider when choosing between a transformer
and a generator?

TIA,
Michael

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.
