UAF13 — Information elements require better definition of relationships

Current implementation of information elements (both Operational and Resource) does not allow for decomposition, which would allow for multiple layers of fidelity to be represented in a model. Most information elements in a real system are "decomposable" in the sense that they can be represented by parts (in the case of a document, multiple data elements may be represented in one Operational element; in the case of a Resource information element, headers and multiple payloads may be represented within a higher level "information" element. The data model is particularly important within the EA reprsenetation of a system.
Generalization is also needed within the information elements; flow properties on intefaces should accept elements of a less generalized implementation.
