FpML Issues Tracker

Summary

The current definition of "Backwards Compatability" is loosely defined. For the fpmlVersion attribute to work backwards compatability will need to be tightened up.

5.5 Backwards Compatibility Where possible, every attempt should be made to keep changes to the FpML schema as backwards compatible as possible. In general, the loosening of restriction, or the adding of new optional elements is backwards compatible. For example, adding a completely new financial product in the form of a new substitutable element to the schema will not affect any existing products and the model is backwards compatible with previous releases.
