Are you suggesting the contradiction in the spec. regarding dash as a
range wasn't an problem?  Or that despite having found the error we
shouldn't have corrected it?

In the case of errors like this, which compromise interop because
different implementations choose different solutions to the problem
created by the contradiction, it is inevitable that resolving this
will mean some existing documents which _some_ existing processors
were happy with become invalid.  The benefits in improved interop are
worth the resulting need to upgrade, in my opinion.

In any case, having said all that as my personal opinion.  The
Proposed Edited Recommendation is just that, proposed, so please
submit a comment to www-xml-schema-comments@w3.org objecting to
erratum E2-18, if indeed you think the problem it addresses [1]
shouldn't have been fixed in this way.
