No, because it is meaningless to "ignore" an assertion that is always  
applied by the provider, even if it is advisory to the client. In  
other words, it is not ignored in associated impact, even if client  
chooses to treat as advisory and "ignore" it.

-- non-wire assertion states something will be done (e.g. logging) -  
this happens, so is not optional.
-- client views this as advisory, so ignores in making request, but  
this is not the same as assertion being ignored in entire process.

The issue here is that optional has a much different meaning than
