NOTE: For feedback related to the OSCAL syntax itself, please create or add to an issue in the NIST OSCAL Repository.

• Where, exactly?

  • For the registry, please indicate the tab and cell, or other clear identifier
  • For the guide, please indicate the section number and printed page number (lower right corner)
  • For the OSCAL XML or JSON files, please indicate XML or JSON; and indicate the line number, field id, or other clear location identifier POA&M Guide Section 3.5.2

• What is your feedback? The guide specifies that all SSP inventory-item assemblies must be duplicated in POA&M local-definitions assemblies. If we are providing the SSP, can we not reference the details from the inventory using the same uuid from the SSP?

• What version of OSCAL are you using? (Check our info on supported OSCAL versions) 1.0.4

• What action would you like to see from the FedRAMP PMO? If we are providing the SSP, can we not reference the details from the inventory using the same uuid from the SSP?

• Other information (e.g. detailed explanation, related issues, suggestions how to fix, links for us to have context, eg. slack, gitter, etc)
