    EQD WG has reviewed this recommendation and decided not to adopt it.

    The reasons:
    “We need to provide an extension mechanism which is visible at design time ( substitution ), as opposed to run time ( xsi:type ) to a select group that understand the technique, and can identify the types which can be used at run time

    A choice group is not extensible, and on extension it is part of the base class, which discourages use of FpML as a library”
