Located some composite distinctions (5)
I believe the answer is:
sited
'located' is the definition.
('site' can be a synonym of 'locate')
'some composite distinctions' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'SITED' is hidden within 'composite distinctions'.
(Other definitions for sited that I've seen before include "Put" , "Placed, located" , "Positioned" , "Situated" , "installed" .)
