They don't have a specific area that is "inside", but they do have two 
sides that can be handled separately. In triangles, the order of the 
vertices determines which side is considered "inside", with bezier 
patches the situation is similar.

There is a demo scene using both UV mapping and interior_texture, a 
rendered image is on the Smellenbergh's site here:

It's the one titled "4-corner uv_vectors, interior_texture".
