User Story

When including multiple primary data-centers in an OSCAL SSP, the validation yields the following error:

[ERROR] [/system-security-plan/metadata[1]] data-center-primary: There MUST be a single primary data center.

We have a customer with multiple primary data-centers, for different regions, and I imagine this is a user story for others as well.

Goals

Modify the data-center-primary constraint to allow for multiple primary data-centers.
Modified constraint:

<expect id="data-center-primary" target="." test="count(location/prop[@name eq 'type'][@value eq 'data-center'][@class eq 'primary']) >= 1">
