1) It recommends [1] the use of the UTF-8 BOM -- that seems . . . odd
   to me.

2) Advice wrt xmlns:xlink is contradictory: I've already filed a bug
   on this one [2].

3) 'void' elements [3] -- the name is non-standard, and the

  "Polyglot markup uses the minimized tag syntax for void elements,
   e.g. <br/>, rather than the alternative syntax <br></br>."

   seems unnecessary to me. . .

  <p /> is mentioned, as not appropriate, but nothing is said about
  <br />, which surely ought to be allowed if possible, for legacy

  The final Note seems odd, and introduces a new name ("self-closing").

4) xml:space and xml:base [4]:

  "The [xml:space and xml:base] attributes are not allowed in polyglot

   -- Should this be clarified to read "not allowed on HTML elements"?
   -- As far as I can see the xml:space attribute is allowed, just a)
      has no effect and b) won't/can't be serialised.  xml:base is
      indeed disallowed.
