Norm Walsh: Version identifiers and XML: continuing the conversation with David Orchard on XML 1.0/1.1
I still haven't really grokked why Dave is so keen on mustIgnore, it really does seem to be making extra work for little gain in an environment with a strict notion of well-formedness.
To avoid all these complications I propose the next version be called XML '05, to be released around 2010, Redmond style.
