Sorry I wasn't clear. I don't mind that there exists a non-proprietary 
method as long as there is also the ability to create proprietary methods. 
In fact I favour it. I think it would be good if we could agree on a 
default standardized method.

But don't think that the existence of PUBLIC in the grammar should be
tied to our figuring out a resolution mechanism for them. You and I
agree that XML documents can be interchanged without a well defined 
public identifier resolution mechanism (using system).

You seem to believe that leaving PUBLIC in the grammar without a 
resolution mechanism will inevitably lead to  interoperability, and 
I don't believe that. I think that it will just lead to people using 
public identifiers in prearranged systems and system identifiers on the 
Web. I believe that PUBLIC is useful without a well defined resolution 
mechanism, through pre-arranged conventions and systems, and you may 
not believe that.

Or, to put it another way: in the days before SOCAT, would it have been
better to have no public identifier mechanism at all? I certainly used
it before there was a well defined mechanism. Author/Editor, in particular
had/has a very powerful mapping format that does many things that SOCAT 
does not.
