Question about final elements and element derivation.

I must be missing something obvious here :( but xsd:element accepts [1]
a final attribute:

> final = (#all | List of (extension | restriction)) 

while I don't see how one can derive an element other than through a
substitution group.

So, my question is:

How can we derive an element by extension or restriction (since
xsd:extension and xsd:restriction aren't allowed directly below
xsd:element) ?

Thanks

Eric (confused).
