I also remember this argument well .. and I actually argued for more 
defaulting: if there was only an <input> in an <operation> default to 
in-only etc..

However, I recall losing that part of the battle :(. So +1 for doing what 
Amy recalls- the default value of @pattern is in-out, no matter what's 
inside the <operation>.
