I think the point at issue actually _is_ a pretty obscure corner
case.  Most people assume dangling references are always an error --
when I explain the DTD parallel they are usually surprised.

I agree it either serves no particular purpose (most applications) or
is downright irritating (a few applications, e.g. data-binding).

_But_ in the particular context of the original request,
i.e. incremental schema development, it _is_ useful.  And it's not
much of an interop issue, because once you're _done_ development,
there ought not to be any dangling refs.

Opinions on keeping or removing this feature for W3C XML Schema 1.1
would be welcome.
