Quite to the contrary! Recall tha the DC.xxx proposal involved
binding DC to a URL. So the local name "ADS" would be clearly
bound to a global pointer to one organization or the other. No registry
is needed. Or to look at it another way: the registry is
the web.

A Proposed Convention for Embedding Metadata
in HTML. 
Reported by Stuart Weibel (weibel@oclc.org)

3. LINKAGE TO THE REFERENCE DESCRIPTION
OF A SCHEMA 

It is judged useful to provide a means for linking to the reference
definition of a schema as well. The proposed convention for doing so is
as follows:

<LINK REL = SCHEMA.schema_identifier HREF="URL">

Thus, the reference description of one metadata scheme, the Dublin
Core Metadata Element Set, would be referenced in the LINK HREF as
follows: 

<LINK REL = SCHEMA.dc HREF = "http://purl.org/metadata/dublin_core">
