Londata, my company, has made a new version of the Londata UML Message Generator available, version 1.0-preview-3. This is (I believe) still the only available software that implements the new ISO 20022:2009 methodology for generating XML Schemas from UML models (as opposed to the older 2004 version of the standard). ISO 20022 is the ISO standard for XML messages for banking and finance, as used on the SWIFT network. ISO 20022 XML Schemas aren't hand-edited in an XML Schema editor as happens with some standards. Rather, they are all generated from UML models so that there is consistency across the XML Schemas, and so that human errors are minimised. The Londata UML Message Generator allows companies to use the same ISO methodology for their in-house XML Schema development and management.
Updated example UML models are now available - MagicDraw and Enterprise Architect example models, and Londata's conversion of the official MagicDraw UML profile into Enteprise Architect format. Enterprise Architect isn't supported yet by the Londata UML Message Generator. The Enterprise Architect examples were done to prove the feasibility of supporting Enterprise Architect for ISO 20022 modelling, MagicDraw having been used during the development of the 2009 version of the standard.
