Catching up on non-QAH business, I have some comments.  Here is the first...

I think the definition of extension is wrong here (also on the Wiki) -- it 
actually reads like a variation on the definition of "extensibility".  Here 
is what Karl wrote [1], which I like:

* Extensibility is the ability of a technology to accept extensions in
a defined way. If the extensibility mechanism is not defined, the
technology is not extensible.
* Extension is an additional feature to a technology which gives the
possibility to extend the behaviour of the technology.
