Hi Marty, 

Thanks for the response.

I am not sure if it should be in the metadata spec or community 
spec (in which case, GRS spec should have something like that), 
but defining new $t type is definitely one way of doing it. 

However, I did not get why this could generate long XRIs. 

Requesting 

=sakimura/($t*pk)

should return a pointer to the public key of  =sakimura, 
and XRI itself does not look very long.
