In article <p0600200abbd4342462e4@[]> you write:

It just prevents the use of *literal* control characters.  &#x07; is
legal regardless of whether it's inside an element or not.

I'll use * to represent a literal BEL character:

  <?foo * ?>

are illegal because they all match

  Char* RestrictedChar Char*

as well as

  TextDecl? content






(Nor does <?foo &#x07; ?>, but character references are not recognised
in PIs.)
