Re: draft proposal for catalog resolution



I like most of this alot. I would certainly support it, and Peter's
simple (but less robust) suggestion as a second choice. One quibble:

These sound like we are specifying a bit of processor user
interface. I would remove the first "At user option" and change 
the second from "At user option, the XML Processor must" to "the 
XML may" -- who are we to say that Netscape (or whoever) must provide 
a catalog escape route?

Let this be an area for market differentation. As long as the processor
faithfully tries to follow the instructions from the author, in the
remote catalog, its mechanisms for finding "better" instructions should
be unconstrained. It could be a remote catalog, a URN resolution service
or annoying popup dialog box. Let the market decide.
