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

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

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?

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