Thanks Terje!
Well, it's good to know that it's at least in the works.  :)

Is it currently possible to validate a page using multiple DTD's?  For example,
suppose I want to validate a document using the HTML 4 DTD, along with an IE
DTD.  I've never tried using more than one DTD in the DOCTYPE definition, only
because I could not find any information about including multiple DTD's.  This
is the only page I found, and it's not exactly explained on this page:


The reason I ask is because if the stuff you were working on is partially
working except for commenting out the DOCTYPE already in the document, then
perhaps it could be partially implemented and you can let the users select DTD's
to use in addition to the one in the document.  Then, once you get it to
correctly ignore the one in the document, you could add that option.  Just an

I've had that running for a while and then broken it more or less
irrepairably in the process of adding some new features. I'm in the process
of reimplementing it. It's the latter part of option #2 that is the
problem. It means you have to fully parse the document to identify any
existing DOCTYPE and comment it out. I'm not quite sure how to do that as
of yet. Perhaps I'll settle for "good enough" rather then shooting for
"provably correct". :-(

That's probably because it's already on the TODO -- mine at least; I dunno
about Gerald's -- and Gerald has approved the strategy (remove defaults and
DOCTYPE sniffing in favour of a user override).
