Hi Doug,

For what respects our own services, we will let you know as soon as 
they are adapted from the old SSAP to the new spec.

I can not talk for the other providers who have published their spectra
in the old SSAP form (see list below), but as I said we are working on
an XSLT to help in their transformation, should they want to use it.
