[Tagging] I have been tagging mosques wrong all along

In the Sahelian Openstreetmap I enjoy tagging mosques because they are 
prominent features, nice for navigation and easy to spot on orbital 
imagery - for me it has definitely turned into a "gotta catch'em all" 
game... And I'm not even Muslim !

The tagging scheme I had settled upon was amenity=place_of_worship + 
religion=muslim (building=mosque if there is a main building) and 
landuse=religious + religion=muslim for the plot.

I have learned from Muslims and confirmed in literature that this 
tagging scheme is wrong: what I considered as the mosque itself is 
merely the main prayer hall. The mosque is actually the whole complex 
that I used to tag as landuse=religious.

So, here is my current position regarding the tagging of mosques:

Single building mosque, no change:
amenity=place_of_worship + religion=muslim + building=mosque

Mosque complex: tag the whole plot (often the perimeter is also 
amenity=place_of_worship + religion=muslim

So, no landuse=religious anymore at all and no building=mosque for the 
buildings inside a mosque complex (building=yes - or, for the 
adventurous, multipart buildings with distinct minaret and dome)

Anyone else obsessed with mosques to give an opinion on this 
clarification - is it correct ?
