Virtual XML - Data Format Description Language (DFDL)

The Data Format Description Language, abbreviated DFDL and pronounced like "daffodil", is emerging as the prime notation for describing mappings between data in formatted files (text as well as binary) and a corresponding XML representation. A DFDL specification takes the form of an XML Schema with "application annotations" that make the correspondence between file characters (or bytes or even bits) and XML data values precise.

You can read more about the DFDL standard on the Open Grid Forum project page,
