... while, I guess, the 'type' keyword indicates what sort of info 
should be forthcoming, and therefore what sort of support oXygen 
might offer for providing it (file chooser dialog, etc.).

My original idea would be covered by this.

Then there are the more complicated possibilities prompted by Eliot's 
request. For example, could the result file name then be something 
like 'out/${tsfn}.xml' (where ${tsfn} is "transformation source file 
name, without extension")?

I can see how more exotic variants, like having the output name 
depend on a runtime parameter, could be pretty far out there.
