Re: FpML-AWG core data types

["Anthony B. Coates (Miley Watts)" <abcoates@xxxxxxxxxxxxxx>]

Just for the purposes of alignment, note that the latest UN/CEFACT core  
data types are listed here:

http://www.unstandards.org:8080/display/ATG/CDT+Catalogue

These are the types that ISO 20022 is aligning with.  This information was  
updated last week at the UN/CEFACT forum in Stockholm.

Cheers, Tony.
