I understand that the regulations don't allow light switches in
bathrooms. For this purpose, what does 'in' mean?

I have an L shaped bathroom, door at the end of the short limb, bath at
the end of the long limb. Long limb 2m wide x 3m long, short limb 75cm
long x 1m wide.

I'd really like to put a standard light switch in the room by the
door. The switch would not be in line of sight from the bath or
shower, it is definitely "Outside zones". I can't stand pull switches
near doors!

So is this permitted?
