Since we are required [1] by W3C Process to submit a *single* vote, John
and I need to determine a CCF position on these suggestions.  This email
is an attempt to do that.

In a (straw poll) scenario where the only proposals put forth are those
below and they are mutually exclusive:

1c http://lists.w3.org/Archives/Public/public-grddl-wg/2007Jun/0331.html
2d http://lists.w3.org/Archives/Public/public-grddl-wg/2007Jun/0355.html
3c http://lists.w3.org/Archives/Public/public-grddl-wg/2007Jun/0333.html

The CCF vote is for 3c

If procedure allows for additional proposals, the CCF vote is
essentially for a hybrid of Harry's suggestion below along with 2d.

In particular, the proposal breaks up the GRDDL 'workflow' into 2
sections (for clarity): transformation application (where the identified
transformations are applied) and transformation discovery (where GRDDL
'snoops' to discover transformations to apply.  In both cases, the
procedure is conditional and depends on if the transform is 'simplistic'
and if an XML Processing Model (yet to be defined) is applied.

== Transformation Application ==

If the transformation is an STP (Simplistic Transformation Processor -
XSLT 1.0 essentially) then:

We use the Minimal XPath Model (MX) as input to the transformation
algorithm, where MX is formulated by the non-validating parsing
mechanisms outlined in proposal 2d.

Otherwise (if for example, the transformation is an XProc document), we
use the original XML document representation as input to the
transformation algorithm.

== Transformation Determination ==

If the GRDDL-aware agent is subject to an XML Processing Model (which
the XML Processing Model WG is chartered to produce) then MX is used to
determine transformations.

Otherwise, the original XML document representation is used to determine
transformations where the formulation of the XPath data model is subject
to the applied XML Processing Model.

The notion of an STP would follow from Harry's wording below:

> "In the case where a GRDDL transform specifies all expected
> pre-processing, then the GRDDL transformation language can/should be
> given as input the representation of the GRDDL source document, not
> the
> node-set derived by the GRDDL-aware agent."
