 2. what happens if the translation feature includes plug-in fragments for
 plug-ins that are not in the current image?
 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
