I really doubt that this will ever happen, but even if it does, it won't be in place for another 10-20 years. In openEHR we differentiate between OBJECT_ID (ids for informational things) and DV_IDENTIFIER, a data type for identifiers of real world obejcts, like drivers licenses and insurance; this latter type contains the attributes you need to indicate the organisation etc.See the data types at http://www.openehr.org/repositories/spec-dev/latest/publishing/architecture/reference_model/data_types/data_types_im.pdf.
