What is the difference between an Information Exchange Package (IEP) and an Information Exchange Package Documentation (IEPD)?

An "Information Exchange Package" represents a set of data that is transmitted for a specific business purpose.  It is the actual XML instance that delivers the payload or information.  (The word "package" as used herein refers to a package of the actual data, not a package of artifacts documenting the structure and content of the data.)  An Information Exchange Package can be prefixed with "GJXDM" or “NIEM” to indicate or highlight that the IEP is GJXDM- or NIEM-conformant, as in "GJXDM Information Exchange Package” or “NIEM Information Exchange Package”  The fact that an IEP is GJXDM or NIEM-conformant may be readily apparent from the context, so it is not absolutely necessary to use the word "GJXDM" or NIEM even if the IEP is GJXDM- or NIEM-conformant.

An "Information Exchange Package Documentation " is a collection of artifacts that describe the structure and content of an Information Exchange Package.  It does not specify other interface layers (such as web services).  It can optionally be prefixed with "GJXDM" or NIEM to indicate or highlight that a resulting IEP is GJXDM- or NIEM-conformant.
