The way I envision it there is no new method.  Consider

Control: <a><b/><c/></a>
Test: <a><b/></a>

Today you get two differences from DetailedDiff: (1) "number of
childern on <a> is different" and (2) "expected <c/> but was <b/>".
I'd like to turn the second into "element <c/> not found".

The other way around

Control: <a><b/></a>
Test: <a><b/><c/></a>

only leads to a single difference from DetailedDiff today: (1) "number
of childern on <a> is different".  I'd like to add "element <c/> not
found".

I wouldn't want to touch

Control: <a><b/><c/></a>
Test: <a><b/><d/></a>

where the only difference would be "expected <c> but was <d>".
