Please review the new section 7 GRDDL Agents
and revised section 8. Security considerations

Change log entry:

Revision 1.218  2007/02/17 00:25:02  connolly
- added GRDDL Agents section, with GRDDL Agent conformance label
- subordinate grddl trace example
- move security considerations after GRDDL Agents section
- fix section numbers

Section 7 is short enough that I'll just paste it in:

7. GRDDL Agents

A GRDDL Agent is a software module that computes GRDDL results of
information resources. Given a URI I of an information resource IR, and
an XPath node N for a representation of IR, subject to security
considerations below and local policy and configuration, a GRDDL Agent

     1. Find each transformation associated with N, i.e. 
             1. each transformation associated with N via the
                grddl:transformation attribute as in the Adding GRDDL to
                well-formed XML section 
             2. each transformation associated with N via HTML links of
                type transformation, provided the document bears the
                http://www.w3.org/2003/g/data-view  profile, as in the
                Using GRDDL with valid XHTML section. 
             3. each transformation indicated by any available namespace
                document, as in the GRDDL for XML Namespaces section.
                Note that this step involves computing GRDDL results of
                the namespace document, recursively.
             4. each transformation indicated by any XHTML profiles, as
                in the GRDDL for HTML Profiles section. This step is
                also recursive. 
     2. Apply each transformation to obtain a GRDDL result.
     3. Merge those GRDDL results.
