I am very new to fpml and financial instruments, but a long time experienced developer specially in xml area. I am now working on a specific mapping from to fpml using XQuery where the source has a bare complex type used to create a “user defined field” for a trade, ndf specifically. I would like to know if fpml schema has a way to extend it by means of ‘any’ or a specific type or element. I am trying to find it, but I assumed asking would go faster and get me acquainted. Thanks.
