Re: keyrefs

I'm all in favour of exploring XML representations of the PSVI (see
e.g. [1]), but simply adding attributes to an XML instance will never
achieve this comprehensively, because you can only apply decoration to
the _elements_ of the instance.  The attributes are left out, and
that's not acceptable.
