my source is in german, sorry. Berlin's Neutralitätsgesetz ( law on neutrality ) mentioned here:
http://www.rbb-online.de/politik/bei...-bestehen.html
it does not mention headscarfs at all, it just outright bans all and everything religious related. no crucifix, no kippa, no headscarf and also no exceptions for pastafarian noodlesieves or turbans or whatever.

government follows wise words here in germany:
"Religion is like a penis. It's fine to have one and it's fine to be proud of it, but please
don't whip it out in public and start waving it around... and PLEASE don't try to shove it down my child's throat."
