===== Statement =====

Each FX logical information structure SHALL specialise one or more Part 2 logical information concepts.

===== Source =====

Part 3, Section 17.6: FX Logical Information Requirements.

===== Rationale =====

Specializing the logical information concepts defined in Part 2 preserves the architectural inheritance established by the platform-independent Logical Architecture while allowing the FX Demo Logical Profile to define information structures specific to the Foreign Exchange Domain. This specialization ensures that domain-specific information structures remain consistent with the common architectural information model while supporting interoperability, governance, architectural reuse, and traceability.

===== Applies To =====

This requirement applies to every FX logical information structure defined by the FX Demo Logical Profile.

It applies specifically to:

  * logical information structure specialization;
  * architectural inheritance;
  * logical information architecture reviews; and
  * profile maintenance.

===== Verification =====

Verification SHALL confirm that every FX logical information structure explicitly identifies one or more corresponding Part 2 logical information concepts from which it is specialized.

Verification activities should include review checks confirming that:

  * every FX logical information structure identifies its parent logical information concept or concepts;
  * specialization relationships are documented;
  * inherited architectural meaning is preserved; and
  * no orphan logical information structures exist.

===== Traceability =====

This requirement preserves traceability between the Part 2 Logical Architecture and each FX logical information structure defined by the FX Demo Logical Profile.
