Yes of course, we could make everything a feature, but, as you say, this 
would not be very sensible. I too prefer to keep <address> as a built-in 

As for SOAP Action -err, the "action" parameter as it's now called-, it 
has recently become a real SOAP feature[1], so it can now be modelled as 
such in WSDL. <soapAction> has thus become syntactic sugar. Personally, 
I'd remove it, in the interest of simplicity.
