Configuration for the binding itself

Does anyone know if there is something to allow configuration for the binding itself (not specific to any thing)?

Example: let’s say I have a thing type provider implementation that can, optionally, retrieve thing types from a URL. I’d like that URL to be configurable but I can’t think of anything (without rolling my own) to do that with…

EDIT: since it’s an OSGI component, I was hoping there is an OSGI configuration service or API that I can get (or something to that effect)

Nevermind - I think this describes it: http://blog.vogella.com/2016/09/26/configuring-osgi-declarative-services/
