Editorial comment - All three of these properties implies
a specific measure across time. So the 'over time' language is 

>AR019.1 Web Services conforming to Web Service Architecture 
>can be reliably
>discovered, accessed, and executed.
>D-AR019.1.1 Web Services Architecture will enable discovery of 
>a relocated
>Web Service.
>D-AR019.1.2 Web Service Architecture will enable the 
>availability of a Web
>Service conveyed, where possible.

I don't understand the 'conveyed' part and I disagree with the 
'where possible' language. I suggest removing the last 3 words.

>D-AR019.1.3 Web Services Architecture will incorporate support 
>for reliable

Editorial comment - Why not use the same language as above and say
"Web Services Architecture will enable reliable messaging."

Also, reliable messaging is useful for all 3 of the interactions with 
a Web Service you have described. Is there any requirement for
specifically applying reliability to invocation/execution?

>AR019.2 The Web Services Architecture enables a conforming Web Service
>implementation to be stable with respect to its definition.

I don't see how this achieves stability. This seems to me to belong 
more in the proposed 'loose-coupling' CSF.
