Tim's intent, I think, was for the name of the TSA to be carried in the 
ds:Signature/KeyInfo/KeyName field.

To help consider your proposal, can we look into how extending the 
time-stamp format would work?  How do you see the current <Tst> and 
<TstInfo> being extended?  Could linking information be added as additional 
"signed attributes" within a <Tst>?  Or would you just re-use the <TstInfo> 
inside a different wrapper?
