https://www.rfc-editor.org/rfc/rfc8785

In case you would like to test what you can do with JSON canonicalization, there are two public Web applications at your disposal:
Using JWS: https://mobilepki.org/jws-jcs
Using an "unwrapped" JWS called Java Signature Format (JSF): https://mobilepki.org/jsf-lab

A real-world implementation from OWASP using JSF: https://cyclonedx.org/use-cases/#authenticity

In Saturn JSF is not only a security solution, it is also used for counter-signatures to simplify state-holding in payment systems:
https://cyberphone.github.io/doc/saturn/hybrid-payment.html#6

By securely embedding related messages in each other (aka "Russian doll"), there is no need for external references to previous messages.

Enjoy!
