Yes you are - you just choose to call it a different name - your explanations 
demonstrate that quite well ;)

However what really concerns me is the non-intuitive nature of the merging 
process you propose. Namely I would not expect the lone <b/> to be present in 
result in the example

Source: <a><b x="1"/></a>
Default: <a><b/></a>
Result: <a><b x="1"/><b/></a>

Even worse was this example 

Source: <a><b x="1"/></a>
Default: <a><b x="2" y="2"/></a>
Result: <a><b x="1" y="2"/><b x="2" y="2"/></a>

There is also no mechanisms in place for element removal. Nor non-cloning of 
default elements or of ...

When you said

I agree which is why I dont like the proposal. It is inflexible and 
non-intuitive ;)
