Sounds good.

What is the reason for this?

The idea is that if a paragraph has class="P1 P2", the attributes of the P2 
style that will apply to the paragraph, are those that are not defined in P1,
right?

Can you give an example of when e.g. a word processor would end up generating 
something like this?

Indeed.

What's the reason for a character run across a paragraph boundary?
(Here again I understand the mechanism, but not the need for it).
