For any particular interchange, you absolutely have to have to a
common format. My opinion is that it is extremely difficult,
however, to find a format that will work across all interchanges.
The reason is that an interchange is defined by both the information
and reason for the exchange. For example, one may have a universal
model that describes an account. The information interchanged about
that account, and the semantics of how that account is described may
vary based on how that account is used. The representation of that
account as part of an insurance transaction using ACORD XML for Life
& Annuity may look very different that using that account for an
equity transaction using FIXML. This example is for illustration
purposes, as I haven't actually checked the XML schemas, but it's
pretty safe to say that there are common entities that both standards
describe with their own nuances. Both are widely accepted industry
standards, so there is no right or wrong, only options.
When groups go out to define standards, it is important to take the
context into account. If you take a structural approach, you may
wind up with a data representation that is structurally accurate, but
not appropriate for any of the contexts in which that data is used.
The good in that approach, however, is that you should have a model
from which all of the context-specific models can be derived.
