Call for Exclusions: RDF/A Primer 1.0

Dear Advisory Committee representative,

This is a W3C Patent Policy Call for Exclusions for the following
Recommendation Track document:

- RDF/A Primer 1.0
  (http://www.w3.org/TR/xhtml-rdfa-primer/),
  exclusion opportunity ending on  9 August 2007

This specification was produced by the following groups:
 - XHTML2 Working Group
 - Semantic Web Deployment Working Group

If you do not wish to exclude patent claims during this exclusion
opportunity, no further action is required.

Participants made a Royalty-Free licensing commitment upon joining these
Working Groups. With the publication of this document, per section 4.1
of the Patent Policy [1] Participants have an opportunity until  9
August 2007 to exclude patent claims reading on this Recommendation
track document. 

Because the XHTML2 Working Group recently made the transition to the
W3C Patent Policy, the 12 March 2007 draft is being handled as though
it were a First Public Working Draft with respect to the W3C
Patent Policy.

Excluded claims are not subject to the licensing requirements of the W3C
Patent Policy for this document. For more information about exclusions,
please see
http://www.w3.org/Consortium/Patent-Policy-20040205/#sec-Exclusion

To make exclusions, please use one of the following forms:

 XHTML2 Working Group: 
 http://www.w3.org/2004/01/pp-impl/32107/exclude

 Semantic Web Deployment Working Group:
 http://www.w3.org/2004/01/pp-impl/39408/exclude

The Patent Policy anticipates that the document will evolve during the
90 days following the first publication.  Per section 4.1 of the Patent
Policy [1], whatever draft is available on 10 June 2007 establishes the
reference material for the purposes of this exclusion opportunity. Just
after 10 June 2007, we will send a reminder and identify the reference
draft. Due to the anticipated instability of the document prior to 10
June 2007, Participants may wish to exclude any claims only after
publication of the reference draft (and no later than the end of the
exclusion opportunity).

Per section 4.2 of the Patent Policy [2], a Participant may resign from
the Working Group before 10 June 2007 and be excused from all licensing
commitments arising out of Working Group participation.

To resign from the Working Group before 10 June 2007, please use the
following form:

 XHTML2 Working Group: 
 http://www.w3.org/2004/01/pp-impl/32107/join

 Semantic Web Deployment Working Group:
 http://www.w3.org/2004/01/pp-impl/39408/join
