examples of ProvenanceAnchor (generalized version of what current Transfer tries to do)
Let's consider vf:ProvenanceAnchor and vf:anchoredWith as working names.
It provides the same provenance tracking capability as using vf:Transfer but doesn't make any assumption about which actions flows will use.
It includes alternative to using sub processes in https://github.com/valueflows/valueflows/pull/386/commits/fab19b610b0548f7beef8df5f18fb29fcd17da13
We still need to see how vf:anchoredWith plays with using vf:trackingIdentifier.
I think to evaluate how it compares to just using granular sub processes we will need to evaluate algorithms and queries required to gather provenance information with either approach.
