RE: Options for dealing with IDs

Someone please explain why this isn't a realistic 
option given an on-demand scenario.  If the DTD/Schema 
were ALWAYS processed, I agree that is a bad thing.
The one thing that jumps out at me is that requiring 
a DTD or Schema just to get at ID declarations is 
a heavy requirement given that the number of 
applications that use IDs is large, so this 
can in fact, become a virtual requirement to 
always get the DTD/Schema.

Is that it?

Isn't this a variation of #1?  I.e. it requires that interoperable 
processing requires fetching and looking in a DTD.  So probably not 
realistic.
