Muse currently only has support for defining operation message types,
but not for notification message types. Would this be something useful?
Related to my previous posting, I have an issue where an underlying
system generates a notification consisting of an array of elements.
Muse doesn't have support for publishing an array of elements. Even if
it does, the client has no way of knowing the data structure of a
notification message, unless they have previous knowledge of the
underlying system and knows to expect certain data types. So I thought
that defining a notification message type in a wsdl might be helpful.
