Hi. A metadata type of, for example, DocLanguage can be defined with num="*" and so can be left empty, but in that case the METS editor still runs it through the validationExpression defined in the MetadataType definition, causing validation failure of blank entries. Is that a correct behaviour?
I tried adding ^$|
in the validationExpression, but the METS editor seems to be reporting a blank entry as having the value ‘{1}’. I’m confused. Again!
Best wishes,
Stephen
