Maybe so, maybe no.  There is the prior question of "Should 'tag' URI's
You may find that there is enough use of other things such as LDAP
Distinguished Names so that this proposal never gains a critical mass of use.

I would say that the way one would use a 'tag' has been inadequately developed
so far.   The activities that handle tags should be identified, in particular
where they yield benefits, and where one is investing effort in creating
The 'requirements' are unconvincing without this.

If you review the current popular uses of real tags, a common function of tags
is to enable relative strangers to associate an article with its proper
context.  If your encoding is not supported by a lookup service, it may not be
used.  Competing symbolizations that _are_ supported by a lookup service
may be
used enough more so that your encoding will be buried and forgotten.  

The choice between LDAP and URN is debatable.  But at least LDAP is a viable
option.  LDAP DNs already embody precisely the same "<who> calls <the item in
question> <what>" logic as the 'tag' proposal.
