availability schema v0.2

[Guy Rixon]

Hi,

I am implementing the getAvailability interface as one of the prototypes
required before VO support interfaces can go to PR. I've posted v0.2 of the
availability schema at

http://www.ivoa.net/internal/IVOA/IvoaGridAndWebServices/availability-v0.2.xsd

This version has two main changes. First, I've included a vr:Contact element
to satisfy the requirement in the text of the spec. Second, I've include a
boolean element called "available" to show whether a running service is
currently available for work. This second element is needed to cover the case
where a service is up but some of its dependencies (DBs etc.) are down so it
can't do useful work.

Cheers,
Guy
