I have now collected all suggestions and agreements reached in the cached
info discussion and made a substantial re-write of the current draft.

Major changes:
- The 64 bit FNV-1 non-cryptographic hash is used to provide a digest over
cached data. All use of hash algorithms has been removed, so also all
elements of hash algorithm agility. The FNV-1 digest algorithm used in this
specification is defined in Annex A.

- It is now possible to query a server with an empty cached info extension
to find out if, and to what extent the server supports caching before the
client starts to cache data for that server.

- The data substitution syntax has been explicitly defined for both defined
object types

I will present the proposed changes at the TLS meeting today.
