That's what i'd understood - that schema describes the infoset and something in each binding describes how that infoset is to be serialised (encoded). 

But on yesterdays call i understood that an MTOM encoding would be flagged
in the schema - which to my mind implies the same serialisation would be 
employed across all bindings ?

XML Schema describes Infosets rather than serializations. So I would
argue one could use the same schema to describe an XML 1.0 and an MTOM
serialization of a message.
