My own answer would be any of those. (I'd rather my car engine computer
didn't come to a hard stop on the motorway just because someone
mis-entered something:-)

Specifically I think it could potentiality be used anywhere were the
consumer of the document has no write access to fix the document. I
wouldn't personally use it on "my" xml as when processing that I want
errors reported so they can be fixed, just as I wouldn't want a C
compiler to fix up syntax errors.

mostly existing (or future content made by existing, dubious, methods)
in particular the vast amount of "xhtml" out there that isn't xml.
Actually if it's only used for xhtml that would still be a win.
It was rather regrettable that the w3c promoted the idea that xhtml 
should be served as text/html (and thus not processed by an xml parser) 
as that had the inevitable consequence that a lot (possibly most) of it 
is not well formed in practice. But what's done is done, and allowing 
those documents to be processed in some standard specified manner would 
be a good thing, I think.

you can have any colour you like so long as it's black (and spelt color:-)

true (and this isn't a wiki and I'm not Anne, but some possible answers
nevertheless...)
