The CA version of the common DAOD physics augmentations (used in PHYS/PHYSLITE etc) do not currently have explicitly written LHE3 weight book-keepers, of the form
It is suggested that adding these may be overspecified since they can be calculated from other metadata. However, since these book-keepers are explicitly written in the legacy version, to ensure smooth validation between the old and new configurations they are added in the CA version in this MR.
The MR is not yet ready as the format of the metadata seems to be available in a variety of forms (lists, strings and dictionaries). Expert assistance will be needed to figure out how to process this information.
