Allow Metadaten Skripte to change ORDERLABEL and LABEL

[andre-hohmann]

Is your feature request related to a problem? Please describe.
With Metadaten Skripte it is possible to change (add, delete, copy, ...) metadata from the dmdSec for many processes.

It is not possible to apply the Metadaten Skripte to metadata with the domain attribute mets:div. This would be helpful to correct existent processes without LABEL or ORDERLABEL attributes. See the following discussions and issues:

• TYP, LABEL und ORDERLABEL in Überordnung speichern #6184
• Automatically set outline headings  #5016

Even if a solution is found to enter the values in LABEL and ORDERLABEL automatically from the respective metadata (title, current number, ...) it is necessary to correct the metadata of many existent processes, which cannot be done manually.

Describe the solution you'd like
It should be possible to apply the Metadaten Skripte to metadata with the domain attribute mets:div according to the metadata without domain attribute mets:div.
