Reserved namespace for private collection?

[Axel Miesen]

Hello group!

I'm playing around with collections these days...

My question: Is there any reserved namespace that could be used for private/local collections, when it is for sure that they will never be published in the Galaxy?

Something like "local" or "private"? If not, and I choose "whatever", should I care if this is eventually used in the Galaxy?

Thanks for your time,
