Wanted: Recommendation for common native metadata keyword for SBOM file links

[sjn]

I think it would be beneficial to publish a recommendation for the name of the keyword used to refer to primary component SBOM documents that an author publishes (or a re-packager packages).
This keyword recommendation is intended for implementors of "native" package metadata specifications for each package ecosystem, with the intention to make it easier for downstream tooling to quickly identify and access any metadata accompanying the package that is in the form of an SBOM file.

It will be interested to define the scope of the sbom we want to reference.
This sounds particular interesting for package managers the bundle packages.
