Not quite. Flow is (roughly) block *and* inline (like %flow in the HTML4  
DTD).

It doesn't have any effect on default rendering at all. The rendering  
section covers default rendering. The content model governs what kind of  
content is allowed as children/descendants of a given element. For  
instance, the content model for <html> is:

[[
Content model:
    A head element followed by a body element.
]]
