Hi Bryan,
The Mortgage Industry Standards Maintenance Organization (MISMO) allows
for extensions in its data standards and this is considered vitally
important. In fact in the last few versions the ability to extend
further and more easily has been pursued. This is primarily because in
the industry there is a limit to what can be standardized-- yet specific
trading partners often have a need to pass additional data on a
transactional level.
As an odd sidenote: in their process of defining standards they (and
others) make ample use of the extension features built into XML
Schemas-- including attributes from other namesapces and documentation
sections containing application specific elements.
Cheers,
Jeff Rafter
