An explanation of an attitude no longer held? (10)

Ross

I believe the answer is:

exposition

I'm a little stuck... Click here to teach me more about this clue!

'an explanation' is the definition.
(I know that exposition is a type of interpretation)

'an attitude no longer held?' is the wordplay.
I cannot quite see how this works, but
'attitude' could be 'position' (position is a kind of attitude) and 'position' is located in the answer.
'no longer' could be 'ex' (prefix meaning former or onetime) and 'ex' is found in the answer.
No letters remain.
This explanation may well be incorrect...

'of' acts as a link.

Can you help me to learn more?

(Other definitions for exposition that I've seen before include "Public display" , "commentary" , "Account" , "large show" , "fair" .)

I've seen this clue in The Globe and Mail.
