Good Day, I would like to extend the Account model type to include an accountType enumeration that is specific to the environment. I have read the Architecture 3.0 Recommendation documentation and tried a first stab at extending the Account node but seem to get into a bind because for example the requestAllocation and other messages use the base Account type and not the extended one. Is there an example of how to achieve this on any of the nodes within FpML? Regards, Mark P Ashworth http://mpashworth.wordpress.com
