Is it a terminology issue, or a deeper problem, that we have both

  When a _foreign element_ has one of the namespaced attributes given by
  the local name and namespace of the first and second cells of a row
  from the following table, it must be written using the name given by
  the third cell from the same row. . . xml:base . . . xml:space

  [Section 8.1.2.3 Attributes, in Section 8 The HTML Syntax]

but also

  Authors must not use the xml:base attribute in _HTML documents_.

  [Section 3.2.3.5 The xml:base attribute (XML only)]

?

That is, the former appears to allow xml:base on foreign elements,
while the latter appears to forbid it.  Please clarify this in the
spec. one way or the other --- our preference would be for the xml:
attributes to be allowed on foreign elements.

I think they should be allowed on HTML elements as well. They can be set by
script, and xml:base might well be useful.
