Fully Deploy OSCAL Metaschema Constraints

[david-waltermire]

Goals

• Design and implement a solution to manage core OSCAL constraints.
  • Ensure necessary Metaschema support for constraints
    • Implement a recursion function to support indexing of identified objects in imported OSCAL content.
    • Ensure indexing supports detecting conflicting entries (Clarify behavior for conflicts in role, location, party, and reference identifiers across imported OSCAL content #1290)
  • Define a model that simplifies the constraint definition process
    • Allow common index constraint definitions to be easily shared between models.
    • Allow allowed value sets to be defined and shared between models, without the need for using XML entities.
    • Support the association of specific property names with their allowed values.
    • Simplify definition of link constraints supporting both direct and resource references.
    • Develop a method to ensure all constraints have an identifier (Constraint Has Its Own Unique Name or ID metaschema#232)
• Review existing constraints for all models
  • Ensure all constraints have an identifier (Add Constraint IDs/Names for All Constraints in Model #1430)

As an epic predating #1688 board reorganization, I will want to label this as needs refinement for now until it can be broken down, rescoped, and or closed.
