The FX Demo Logical Profile sits between the reusable Part 2 [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_model|Logical Model (LM)]] / [[dido:99_annexes:annex-b-terms-and-definitions:p:platform_independent_model|Platform Independent Model (PIM)]] and later implementation, deployment, testability, and [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]] layers.

Part 2 defines the reusable, distributed, node-based [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_model|Logical Model (LM)]] / [[dido:99_annexes:annex-b-terms-and-definitions:p:platform_independent_model|Platform Independent Model (PIM)]]. This part specializes the Part 2 logical architecture for the [[dido:99_annexes:annex-b-terms-and-definitions:f:foreign_exchange_domain|Foreign Exchange Domain]]. Part 4 maps selected FX logical profile elements to implementation artifacts. Part 5 defines deployment, testability, runtime operation, and [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]] collection for the selected implementation.

Figure 5-3 shows the position of Part 3 within the document-set layering model.

<code>
Part 1: Conceptual Architecture
└── Part 2: Distributed Node-Based Logical Architecture / PIM
    └── Part 3: FX Demo Logical Profile
        └── Part 4: Phase 0 Implementation Profile / PSM
            └── Part 5: Phase 0 Deployment,
                         Testability, and Evidence Plan

The FX Demo Logical Profile therefore acts as the domain-specialization layer. It provides enough FX-specific logical detail to support implementation mapping and [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]] planning while preserving platform independence.
