You mentioned browsers that expect a space before the tag closing. Some browsers are peculiar about enclosing attribute values with single quotes instead of double quotes (Openwave browsers come to mind). But in all these cases, the quirks do not contradict the well-formedness of the markup. In other words, requiring well-formed content is perhaps not enough, since additional constraints must be satisfied, but it is a minimum. As I suggested:

    "Can we state that the transformed
    content returned to the terminal must
    at least be well-formed (following XML
    terminology)?"

I reiterate my question: does anybody know of a browser that will process content properly _only_ if it is _not_ well-formed -- e.g.  omitting the XML declaration, leaving tags open, parsing only uppercase element names, duplicating attributes for the same element, overlapping elements instead of nesting them, whatever? 

If not, the requirement for well-formedness could indeed constitute a minimum requirement -- not an "all clear", but a "seems basically ok".

> Validation, however, is another matter...

I already agreed that requiring validation (in the XML sense) is probably too much.
