There is no central registry of DTDs that I know of, but my consultancy
is registering under ISO 9070 with the GCA, so the current FPI will
eventually get a + at the start instead of a -. Ideally a 9070 server
could locate the Public Owner's coordinates in cyberspace and look in
some de facto or de jure directory for the specified DTD, eg

   <!doctype html "+//FooBar/DTD HTML X//EN"> 

Could be interpreted as "find www.foobar.com" and when found, 
"look in /dtd for html_x.dtd".

Parsing browsers like Panorama still need to pick up directions via 
an entity management system, but I see no reason why the future should
not permit the SYSTEM component of a DOCTYPE declaration to be a URL:

<!doctype html public 
 "-//FooBar/DTD HTML X/EN" "http://foo.bar.com/somewhere/my.dtd">

Does anything support this yet?
