What is a view, and can one define an arbitrary one?
A view is a particular, required, collection of the information components contained in a trade. Typically a view is processing service specific in that it is the subset of elements that must be in the Trade element for a service to function properly. For example, one might have a matching service that needs the trade ids, product, parties and fee elements in order to do a match, whereas a pricing service where clients can store their portfolios might only need the trade ids. Currently there is no mechanism to express a view. This issue should be revisited in the context of business events and processing before the first public release.
