5. Task Force Status.
a. Properties and Features (dormant)

<scribe> Sanjiva: worried about how the Patterns proposal will impact the
spec

a narrower definition
<scribe> David: Sanjiva was concerned about specific patterns
<scribe> David: many patterns are recognized in the TF proposal. That does
not mean the TF is recommending all of them for the spec

<JacekK> q+
<scribe> Jonathan: experimented with the extension
<scribe> Jacek: proposes to add specific wrapper elements for signatures
<scribe> Jacek: wrapper elements are orthogonal to general extensions
<scribe> Roberto: prefers to remove the substitution groups and go back to
using element wildcards
<scribe> Jacek: does not like to have two ways to define the same thing
<JacekK> +1 to poll
<sgg> +1 to poll
* JacekK thinks the poll could include the third option
<scribe> Jonathan: poll?
<scribe> Umit: needs more time to think about this
<scribe> Jonathan: Roberto to rewrite up an email about these
<sgg> would the wsdl:rdf element be required for support by WSDL processors?
<Philippe> ACTION: Roberto to rewrite up an email about these
* RRSAgent records action 1
<JacekK> the wsdl:rdf element could be ignored completely by processors not
interested in the RDF representation of the WSDL doc

Comments on the pretty pictures [.3]. Simplification of the
Simplification proposal [.4].

of adopting the single service per interface proposal
* Philippe notes that no one supported serviceGroup during the f2f meeting
<scribe> David: two questions: one for targetResource, and one for single
service
<scribe> ACTION: Igor to write up about pros and cons of the single service
proposal
* RRSAgent records action 2
<scribe> Arthur: would be nice to have programming language interfaces
mappings
<scribe> Amy: not in favor of Arthur's proposal, wants to keep WSDL language
independent
<scribe> Jonathan: introducing language bindings without impacting other
WSDL offerings is nice
<scribe> Umit: simplification introduced by adopting single service per
interface may benefit people down the road

<scribe> It is a GRID requirement
<scribe> Sanjiva: targetResouce is more dynamic
