Correct. The problem isn't actually that Python keywords are used in 
ZCML (they can be, of course), but that we use schemas to describe ZCML 
directives and there we can't use keywords. That's why we append an 
underscore. The APIDoc tool shouldn't really print that. It should print 
what the user puts into ZCML...
