Re: [dix] Permanent IDs and how to obsolete an identity

[Charles Carrington <cdcarr at us.ibm.com>]

Lisa,

I think its virtually impossible to
remove anything completely from the Web.

I think we should concentrate on expiring
the credentials associated with IDs.   Driver's licenses and passports
have expiration dates.  PKI certs
have expiration dates and revocation lists.  Most ID's do not, and
I think this is 
a feature that is sorely needed.

Thus "permanent IDs are not allowable"
might be a better approach.
