Experimental Algorithms again

[Stefan Lorenz]

Hello,

I am sorry for posting again, but we didn't find a solution to the 
problem yet and didn't get any responses so far.

The main question is, whether it is possible, maybe using the Algorithm 
type 100 (experimental), to attach own (key)data for an additional 
algorithm, to an existing gpg key, or to import it into the keyring as a 
standalone key. So far we achieved importing a key with experimental 
algorithm type into the keyring, however we could not construct a valid 
self-signed UID packet. We appreciate any hints on whether this is 
possible at all and if so, how.

Best,
Stefan
