2. what happens if the translation feature includes plug-in fragments for

	does it load correctly and ignore those fragments? if so, good
   A: warnings appear in the run-time error log
	does it fail to load? if so, then we need to generate different features, perhaps
		one feature for each plug or else we need to know more about the project
		distro structure to know which plug-ins to put in each feature
	what happens if those plug-ins are later added - does it load the strings now?
   A: probably not
3. need to handle different versions of each feature/plugin/platform; generate different
	language packs for each
