Clarification on Allowed Signature Algorithms: RSASSA-PSS vs. RSASSA-PKCS-v1_5

[uwsrf]

In the C2PA Specifications version 2.1, there seems to be a discrepancy regarding the allowed signature algorithms:

In section 13.2.1., the listed signature algorithms include only RSASSA-PSS for RSA-based signatures.
However, in section 14.5.1.1., the examples refer to sha256WithRSAEncryption and similar signatures, which are defined in RFC 8017, Appendix A.2.4 describing RSASSA-PKCS-v1_5.
This raises the question:
Is RSASSA-PKCS-v1_5 also allowed alongside RSASSA-PSS, or should it be considered deprecated/unsupported?

Could you please clarify the intended scope of allowed RSA signature algorithms in the specifications?

Thank you!
