Annex A: Acronyms
Scope
This annex identifies acronyms that are used within the FX Demo document set and are not defined in the General Annex A: Acronyms.
The General Annex A remains the controlling source for acronyms used across multiple DIDO Solutions specifications. This annex contains only acronyms that are specific to the FX Demo or its financial, operational, and implementation context.
An acronym defined in the General Annex A is referenced directly and is not duplicated here.

Maintenance Rules
-
Include only acronyms that appear in the FX Demo document set
-
Check the General Annex A before creating an FX Demo acronym entry
-
Link to the controlling general entry when it already exists
-
Add broadly applicable acronyms to the General Annex A rather than this annex
-
Maintain each FX Demo-specific acronym as an individual leaf page
-
Organize acronym pages under the initial letter of the acronym
-
Do not add a trailing `:start` to an individual acronym page
Notes for Editors
Review Parts 0 through 7 periodically to identify acronyms that have been added, removed, or revised.
An acronym should not appear in this annex merely because it relates to foreign exchange. It must appear in the FX Demo document set and must not already have a controlling entry in the General Annex A.
