copies

> replication of the directory structure for DTDs.
> 3. Moving forward, we might want to look at an automated discovery
> mechanism for DTDs. Maybe we could use XML-RPC or SOAP for that purpose?
> This tool would offer a DTD write a chance to not only populate the
> directory but also distribute updated copies of a DTD.
