Review Top-Level Model Indices and Supporting Constraints

[aj-stein-nist]

User Story

As a NIST OSCAL developer, in order to be confident of a thorough model review to tighten up docs and supporting constraint and index definitions for programmatic use in Metaschema-aware libraries, I would like an updated review of models for missing top-level indices and supporting constraints.

Goals

• Review and add missing indices that add useful or necessary indices for all top-level OSCAL top-level models (catalog, profile, SSP, AP, AR, POA&M)
• Review and add supporting constraints that logically flow from just those index updates as applicable with discussion of team during review

Original rationale and goals can be found in the comment, leading to the creation of this issue.

Dependencies

• Update Metaschema syntax for constraints to have identifiers and potentially auto-generate them in Constraint Has Its Own Unique Name or ID metaschema#232
• Completion of Review Control layer models #1331 and merge of Updates to OSCAL Metaschema documentation and constraints #1263
• Additional potential deps as confirmed by Dave upon prioritization of this story

Acceptance Criteria

• All OSCAL website and readme documentation affected by the changes in this issue have been updated. Changes to the OSCAL website can be made in the docs/content directory of your branch.
• A Pull Request (PR) is submitted that fully addresses the goals of this User Story. This issue is referenced in the PR.
• The CI-CD build process runs without any reported errors on the PR. This can be confirmed by reviewing that all checks have passed in the PR.

This is very open-ended and needs to broken down and organized to delegate to developers to work. Per discussion with Arminta, marking this as needs refinement.
