I'm behind, but this is going more slowly than I had hoped, partly
because I'm finding the structure of the document inimical to finding
answers to my questions easily -- that's in itself an issue, but one I
can't formulate concretely yet. . .

I've attached my raw notes, which are complete up through the end of
section 2.4.

Specific issues meriting consideration:

 1.4 implies XForms _could not_ be reconstructed within HTML, which is
 a best contentious and at worst manifestly false, and appeals to an
 unidentified decision about "the previously chosen direction for the
 Web's evolution".

 1.7 Is HTML5 two things or three out of the following?:
    1) An abstract language;
    2) In-memory representations of resources that use that abstract
       language;
    3) Concrete syntax

 2.2 Document conformance and implementation performance are in
 principle decoupled, with the consequence that every document-content
 'must' has to be checked against the parser, and every 'parse error'
 or algorithm 'fail' or 'abort' has to be checked against the document
 constraints.  Which, if either, of these is the so-called authoring
 spec. based on?

 2.4.2, 2.4.3 -- two changes from XHTML/HTML 4.01, one more
 restrictive, one less -- a general issue -- are these changes a)
 tabulated anywhere, b) motivated?

 [no specific locus] There's a strong implication, if not an
 explicitly stated requirement, that only character sequences are *XML
 documents*.  This appears to rule out the possibility of conformant
 processing of XHTML in e.g. a pipeline processor.  There is a more
 general problem in that the word 'document' is used both of character
 sequences and of DOM *Documents*, and it is not always clear what
 constraints apply to what.
