new IVOA Registry Interface Spec

[KevinBenson]

There is a new Registry Interface Spec at
http://www.ivoa.net/twiki/bin/viewauth/IVOA/RegistryInterface  also uploaded
it as a working draft at the document submissions page for IVOA.

Because the IVOA document submissions page does not let you start off with a
version 0 to make a 0.02, I went ahead and renamed this version 1.02.  If
this is not proper then we can change it back and instruct me on how the
version numbers work, but I suspect we should keep it with what is
submitted/uploaded to IVOA.

Please have a look at this new document it has much more detail than before,
several issues I can see needs to be discussed.  I have began adding a few
comments at:
http://www.ivoa.net/twiki/bin/view/IVOA/InterOpMay2005ResRegIssues  (but
this should be moved to the mailing list or another wiki page later.)

Currently only in doc format tomorrow morning Friday March 3rd, I will
upload it as a pdf.

Cheers,
Kevin
