[csae8092]

establish some coding guidelines with examples on how to document who did what and when in the tei:revisionDesc statement; ideally use some fixed termes/phrase like

• finished criticial apparatus
• added notes
• tagged and linked entities
• ...

(so basically what we are doning in the AMP-Project https://github.com/Auden-Musulin-Papers/amp-data/blob/0fa15837421ddce86a78b5defa4d65b70bd13cb2/data/editions/amp-transcript__0001.xml#L89)
