The thing I don't like about this is that it looks that same as:
  <field type="CARD32" enum="Enum" />

But means something entirely different.

What might be clearer is for the enum values to be marked as "This
enum value is a valid value of type PIXMAP".  Then the more-typeful
programming languages can generate typed constants.

Presumably it would look like:

  <field type="CARD32" enum="reference:Enum" />

Like we do in other cross-namespace types.  Is that what you were thinking?
