Well, we can't vote yet, but we will be able to very soon. Lauren
suggested that it might be useful to have a preliminary discussion of
the requirements. I'm attaching the current version. Comments?

This document lays out the requirements for developing an XML-based version of [TR 9401:1997].

• The catalog must be expressed in XML ([XML]) with a specified namespace ([XML Names]).

• The catalog must provide the ability to map public identifiers to URIs.

• The catalog must provide the ability to map system identifiers to URIs.

• When both a public identifier and a system identifier are present, the author of the catalog must be able to express which should be used preferentially.

• The catalog must support xml:base ([XML Base]).

• The catalog must provide the ability to delegate mapping of classes of public identifiers and URNs to alternate catalogs.

• The catalog must provide the ability to map notation names to URIs.

• The catalog must provide the ability to map entity names to URIs.

• The catalog must provide the ability to map URIs to alternate URIs (for example, namespace names).

• Where the functionality of the XML catalogs developed by this Technical Committee is equivalent to functionality provided by TR9401:1997 Catalogs, the semantics must be identical.

• The catalog must provide an extension mechanism for experimental additions to the catalog.
