let authors choose text/html or application/xhtml+xml (detailed review of section 1. Introduction)

Regarding this paragraph:

"XHTML documents (XML documents using elements from the HTML namespace)
that use the new features described in this specification and that are
served over the wire (e.g. by HTTP) must be sent using an XML MIME type
such as application/xml or application/xhtml+xml and must not be served
as text/html."

XHTML documents served as text/html result in interoperable behavior
in typical cases, so that constraint is too strong. Please change
it to "SHOULD be sent..." and "SHOULD NOT be served...".

6. Guidance in the use of these Imperatives

   Imperatives of the type defined in this memo must be used with care
   and sparingly.  In particular, they MUST only be used where it is
   actually required for interoperation or to limit behavior which has
   potential for causing harm (e.g., limiting retransmisssions)  For
   example, they must not be used to try to impose a particular method
   on implementors where the method is not required for
   interoperability.
