First, after the decision for Issue 26, we changed the semantics 
of oneOrMore so that it disallows colliding attributes.  One could 
thus argue that the keyword oneOrMore represents two different constructs: 
one is to allow repetition of elements freely and the other 
is to allow non-colliding repetition of attributes.

Second, the BNF created by James becomes simpler if we disallow 
coexistense of attributes and elements in <oneOrMore>.  We can 
get rid of "repeatable"

Sounds good to me. 

Is repeatable used for anything else?
