RE: Issue 217: Syntax for multiple styles

my (probably confused) thinking:

1) this puts 'style' firmly into the realms of an optional extension. 
someone not interested in a given namespace can more easily ignore it.
we can't mark extension attributes as 'required', no? 

This demotion of style is a good or bad thing depending on your POV 
 - i think it's a good thing.

2) it actively encourages other style related extensions to be provided
as other attributes in the 'foo' namespace, e.g.:

     <operation foo:rpc="true" 

this is again, good or bad depending on your POV.
 - i think good!

3) it allows for multiple styles to be easily attached to an operation,
as in Mark's foobar example.

 - good in anyone's book, surely.

So that's a big +1!

Talking about style, I guess you really meant  foo:rpc="true"? ;-)

Yes, let's separate the semantics (and have XML do the parsing for us).

+1. (I guess it's all backwards.)
