Unimarc Default framework When saving a record, the message: Tag 600 subfield a Entry Element in tab 6 Tag 601 subfield a Entry Element in tab 6 In Unimarc fields 600 and 601 are optional.
712$5 also are optional
Any chances you could provide a patch yourself?
Yes, I can fix it myself, but I don't fix the "Default framework" so that there are no problems with updates.
Changes to the default frameworks (the YAML files) won't have an inmpact on updates or existing translations, but they will impact new installations.
He can't provide a patch, because bug 30373 already made 600$a and 601$a not mandatory, and from its first rewrite patch 712$5 wasn't mandatory. Since Koha has chosen not to change anything in frameworks on existing installs, there's nothing that can be done here (other than assuring him that it won't in any way affect updates if he manually makes them not mandatory in his install's default framework).
