First Principle?
There is a thinking that what is seen from the air/satellite is what 
should be mapped.
However in a multistory buliding .. what are people coming to the 
building for? Should 'we' not map the purpose of the building rather 
than just the air/satellite view?For a shopping complex .. that would be 
each shop - location, name and serevice. Provision of parking may be 
important .. but it is not the most important thing. Only a single 
purpose parking complex has the sole function of providing parking.

Second .. Effort?
A miltistory thing will have many surfaces, one floor may be concrete, 
another carpet, another stone. Tagging these in some sensible way may be 
fine .. but how will they be used? And is it worth the effort? 
Considering the quality of the map in some parts of the world would not 
these efforts be better spent in improving the map elsewhere? :)

Presently considering a holiday in India .. and making editorials there 
to get the routing working (and adding things as I see them while doing 
those corrections).
