Is that a tool? Or an Import and Export wizard? Based on your questions 
it sounds like you are asking about a Tool. I would like to ask what 
your workflow is ... what steps does a user take to import / export a 
map format?

Applicability has to do with if the tool is enabled for that layer or 
not. You can turn off editing for one layer, (or selection for that matter).

Looking at the docs:

Did not answer our questions; we will ask Richard when he get's back 
(tomorrow?) and if not it would be time to read the javadocs and experiment.
