Hi Walter,

fyi: The compliance regime can define "qualifiers". I.e., the 
alternative would be to define "1" and "3" qualifiers in compliance 
(while omitting this in the TPE).  This means that 1 and 3 would have a 
meaning/semantics that is defined in compliance and specific to this 
compliance regime.

By defining 1 and 3 in TPE, these concepts would be defined once for all 
potential compliance regimes. This makes sense if it is likely that many 
compliance regimes need this distinction in the way we define it. If the 
idea of elements "not to be re-used by other sites" is specific to our 
compliance regime, we should rather define it there.
