Add Prepared For Constraints

[Gabeblis]

Committer Notes

Purpose

This PR introduces three constraints aimed at ensuring FedRAMP compliance for the digital authorization package by verifying the prepared-for roles/parties. These constraints ensure that all required elements are present and that necessary information is accurately documented.

Changes

Constraint: role-defined-prepared-for

• Validates that there is a defined role with the ID "prepared-for".

Constraint: responsible-party-prepared-for

• Ensures that a responsible party is assigned to the prepared-for role.

Constraint: responsible-party-prepared-for-location-valid

• Validates that the party assigned to the prepared-for role includes a location-uuid with the required address details.

Tests

• Added invalid test data files for all three constraints.
• Added pass/fail YAML files for the three constraints to verify their functionality.
• Updated ssp-all-VALID.xml to contain the required information so that the constraints fire and pass as expected.

Can you address the updated AC requirements in the issue? Sorry again.

Resolved here: 045e70e. I added the check for an embedded address assembly in the party and I added another -VALID.xml test file in order to validate both scenarios.
