As I've been going through the effort of defining a number of Atom
extensions, I've consistently come back to the thought that it
would be interesting to explore the creation of a "Common
Extensions Namespace" under which multiple standardized extensions
can be grouped. I've written an initial draft of the concept but
before I submit it as an Internet Draft, I'd like to get some
feedback from the group. Please review the attached and let me
know what you think.

1. Introduction
The Atom Common Extensions Namespace is a single XML Namespace with
which standardized Atom 1.0 extensions MAY be associated. This
document defines the common namespace and creates an IANA
Registry of
Atom Common Extensions.
2. Notational Conventions
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in
this
document are to be interpreted as described in BCP 14,
[RFC2119], as
scoped to those conformance targets.
3. The Atom Common Extensions Namespace
The Atom Common Extensions Namespace is an expansion of the Atom
1.0
Syndication Format XML Namespace. XML elements and attributes
defined as Atom 1.0 Extensions that are standardized in
accordance to
the process specified in "Section 4: Registry of Atom Common
Extensions" MAY use the Atom Common Extensions Namespace as an
alternative to defining their own extension specific XML
namespaces.
The Atom Common Extensions Namespace
"http://www.w3.org/2005/Atom/ace"
4. Registry of Atom Common Extensions
This specification defines a Registry of Atom Common Extensions
maintained by IANA. The members of the Registry consist of Atom
1.0
Extensions that define XML elements and attributes falling under
the
the Atom Common Extensions Namespace. New assignments are
subject to
IESG approval as outlined in [RFC2334]. Requests should be made by
email to IANA, which will then forward the request to the IESG
requesting approval. The request should use the following
template:
o Name: (A unique informal name by which the extension can be
referred.)
o Description:
o Elements and Attributes: (definitions for each of the XML
elements
and attributes to be associated with the Atom Common Extensions
Namespace)
o Security Considerations:
Extension elements and attributes introduced by new assignments to
the registry MUST be uniquely named within the Atom Common
Extensions
Namespace and MUST NOT duplicate the function and purpose of other
elements and attributes specified by other extensions in the

registry.
5. Security Considerations
There are no security considerations introduced by this
specification.
6. IANA Considerations
This specification creates a Registry of Atom Common Extensions as
described in section 4.
