the introduction says:

It is often valuable to be able to serve HTML5 documents that are also valid
XML documents.

It would be better to say

It is often valuable to be able to serve HTML5 documents that are also well
formed XML documents.


that is "well formed" as opposed to "valid" since most documents conforming to
this spec are not valid according to the XML definition of validity. No
documents using the preferred doctype <!DOCTYPE html> can be valid, the only
ones that can be valid are documents that (a) use an xhtml1 "legacy" doctype,
and don't use any new html5 features.


A related, but separate issue that has been commented on before is that this
document would be clearer (and shorter) if it restricted itself to the
additional constraints that need to be followed to get compatible doms from
html and xml parsing, given a document assumed to be valid html5 and well
formed xml.
So requirements like DOCTYPE being uppercase and attribute values being quoted
could be dropped as they are implied by the document being well formed.
