leaded

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

'remove content describing cathedral's windows?' is the definition.
I can't tell whether this definition defines the answer.

'guide edited' is the wordplay.
'guide' becomes 'lead' (lead can mean to usher or guide).
'edited' becomes 'ed' (publishing abbreviation).
'lead'+'ed'='LEADED'

'to' acts as a link.

Can you help me to learn more?

(Other definitions for leaded that I've seen before include "Petrol with Pb" , "Older type of petrol" , "Not "green" petrol" .)

I've seen this clue in The Irish Times.
