Proposal 1c (transformation domain) to address the ambiguity issue

Message-ID: <EBBD956B8A9002479B0C9CE9FE14A6C202D33524@tayexc19.americas.cpqcorp.net>
To: <public-grddl-wg@w3.org>

This supercedes proposal 1b.  It is the same except that parts related
to defining the notion of "complete GRDDL results" have been eliminated.

This proposal changes the input of a GRDDL transformation from an XPath
node tree to the original XML document representation, so that
transformations can control the parsing if desired.


PROPOSAL #1c: In the following existing normative text:
http://www.w3.org/2004/01/rdxh/spec#rule_result 
[[
If an information resource([WEBARCH], section 2.2) IR is represented by
an XML document with an XPath root node R, and R has a GRDDL
transformation with a transformation property TP, and TP applied to R
gives an RDF Graph[RDFC04] G, then G is a GRDDL result of IR.
]]
change "XML document" to "XML document D"
and "TP applied to R" to "TP applied to D".
And make corresponding changes to the informative text in section 6 and
elsewhere as needed.

ANALYSIS: 

 - This change does not require any changes to the test cases.

 - This is only a partial solution to the ambiguity problem, because
there would still be ambiguity in the determination of what GRDDL
transformations to apply.  (Proposal 2c further addresses that
ambiguity.)
