Q26543628 does not capture 'variable' encoding, nor complete signature correctly (PDF/A-1b) #7

Description of problem

There are two signatures that should be associated with Q26543628. Both should have a BOF sequence (PDF...) and then each should have one variable position sequence. The Wikidata record aggregates all of this information incorrectly so there are only three sequences and so it looks like there are two variable sequences with one BOF. This makes it difficult to infer how to use these sequences. Initially I think we'll have to leave it out of the first Wikidata signature file, and then we'll need to fix up the record.

The variable sequences I understand to be there by looking up PRONOM at the same time. The variable sequences are not explicitly described as Variable in WIkidata.
