I disagree, You canonicalize a document subset and the IDs move from one 
element to another. That sure feels like ID breakage to me (though one 
caused by a design flaw in canonicalization).

Worth noting: you don't have this problem if you only do whole document 
canonicalization.

It's not the implementations that have this problem. It's the spec. All 
conformant implementations have this problem.
