Re: [wsrf] [Issue WSRF9] summary of alternatives

Dave:
I did spend some time thinking about
an approach similiar to your suggestion.  What stopped me from including
a write up of this approach in the proposal was:

a) it is non trivial to take an existing
schema document, find the xsd:any and then insert additional elements around
it.
b) if we did an approach such as a),
there is potential confusion for various consumers of the resource property
document.  Which of the now many "authoritative sources for the
schema of that document" is in force at any one time?  If the
RP is added and then removed, there is a potential for significant problems
when the schema a requestor has in hand is somehow "out of sync"
with the current version reflecting the current set of dynamic resource
properties.  
Therefore, I am being conservative here, and chose not to include this
approach.
c) even if we did make the behavior
suggested in a) a SHOULD, it still leaves the requestor unclear over how
to answer the question, especially when dealing with services that chose
to interpret SHOULD as "OK TO IGNORE" (ie not implement).
d) the proposal was getting too big
already, and I was tired of typing :-)

Steve,

Let me show some ignorance. You wrote:

Why can't we specify that any dynamic properties have their schema 
added to the wsrp:ResourcePropertyDocumentSchema on the fly? We could 
make it a SHOULD if it seems a bit demanding for some implementations.
