Can I use BIAN to model the whole Banking/Financial Services ecosystem?

It is intended that the BIAN Service Landscape will eventually include Service Domains covering all activities in the Banking ecosystem. At this stage it only covers the majority of products and services for banks but is missing Service Domains supporting several areas such as trading market operation, some key market support functions and the merchant relationship side of cards. These extensions will be added as members expand the model into additional areas of interest. The expansion will simply add additional Service Domains and should not change existing elements of the standard. In the meantime it is possible to add candidate Service Domains as necessary that anticipate these formal extensions.
