I think we can agree that the error handling should be, at the option of 
the software developer, either to handle the input as defined by the 
spec's algorithms, or to abort and not handle the input at all.

Having multiple specs means an implementor has to refer to multiple specs 
to implement one algorithm, which is not a way to get interoperability. 
Bugs creep in much faster when implementors have to switch between specs 
just in the implementation of one algorithm.

I'm not saying we should increase the space of valid addresses. The de 
facto parsing rules are already complicated by de facto requirements for 
handling errors, so defining those doesn't increase complexity either 
(especially if such behaviour is left as optional, as discussed above.)
