The XProc specification had been published on 5 January 2010 at
http://www.w3.org/TR/2010/WD-xproc-20100105/ as a third Last Call. The
LC review period ended 2 February 2010.

The LC comments have been considered and resolved, a notification of
the resolution sent to every commentor, and acceptance of the
resolution by each commentor is recorded in the DoC at

The XProc specification had previously been published on 28 May 2009
at http://www.w3.org/TR/2009/CR-xproc-20090528/ as a Candidate
Recommendation. Reports from implementors about the CR draft were

During the course of CR, we encountered significant community feedback
about the language versioning story. Although the feedback was not
strictly speaking from implementors, the WG was persuaded to revisit
that part of the specification and to address the concerns expressed.
We returned to Last Call after making these changes in order to give
the community opportunity to review them.

Because of the previous successful CR, the XML Processing Model WG is,
at this time, requesting a transition directly to PR. (The DoC for the
previous CR draft can be found at

As indicated in the Implementation Report at
http://tests.xproc.org/results/comparison.html the implementation
feedback has been positive.

A review version with changes highlighted is available as referenced
in the "This document is also available in these non-normative
formats" section of the latest draft document.

There have been no changes in patent disclosures since LC:
http://www.w3.org/2004/01/pp-impl/18796/status#disclosures (there are
no disclosures).

The WG's decision to request transition to Proposed Recommendation was
taken during a teleconference on 25 February 2010 whose minutes may be
found at http://www.w3.org/XML/XProc/2010/02/25-minutes


We propose a publication date of 9 March 2010.

XProc: An XML Pipeline Language


   This specification describes the syntax and semantics of XProc: An XML
   Pipeline Language, a language for describing operations to be performed on
   XML documents.

   An XML Pipeline specifies a sequence of operations to be performed on zero
   or more XML documents. Pipelines generally accept zero or more XML
   documents as input and produce zero or more XML documents as output.
   Pipelines are made up of simple steps which perform atomic operations on
   XML documents and constructs similar to conditionals, iteration, and
   exception handlers which control which steps are executed.

   Though the previous version of this document was a Last Call Working
   Draft, there was an earlier Candidate Recommendation version of this
   document that has already resulting in successful implementation feedback.
   Given that the changes to this draft do not affect the validity of that
   earlier implementation feedback, except in specific areas also now covered
   by more recent implementation feedback, the Working Group is now
   publishing this version as a Proposed Recommendation.

   There is an Implementation Report for XProc.

   W3C Advisory Committee Representatives are invited to submit their formal
   review per the instructions in the Call for Review (see Advisory
   Committee questionnaires). The review period ends on 15 April 2010.

   This specification implements all of the requirements documented in
   [XProc Requirements].

   Publication as a Proposed Recommendation does not imply endorsement by the
   W3C Membership. This is a draft document and may be updated, replaced or
   obsoleted by other documents at any time. It is inappropriate to cite this
   document as other than work in progress.

   This document was produced by a group operating under the 5 February
   2004 W3C Patent Policy. W3C maintains a public list of any patent
   disclosures made in connection with the deliverables of the group; that
   page also includes instructions for disclosing a patent. An individual who
   has actual knowledge of a patent which the individual believes contains
   Essential Claim(s) must disclose the information in accordance with
   section 6 of the W3C Patent Policy.
