With Zotero3.0m297 (=MLZ) the "punctuation-in-quote=false" becomes valid as soon as Zotero->Preferences->Languages->CSL=German.
For all those out there, who want the comma outside the quotes: There must be: 1) an entry inside the .csl-File within the locale portion: <locale> <style-options punctuation-in-quote="false"/> </locale>
AND
2) Zotero MLZ: Preferences->Languages->CSL=German Standard Zotero: The CSL-Language must be somehow set to German. I do not know how.
Thank you guys for the quick responses! This is awesome.
