-There is an excellent article - [Attribute Customization – Java Based Value Providers, Conditions and Validators]() - written by @rsjazz which explains in great detail the diffrent ways that RTC offers to customize attribute behavior. The section _"Value Set Provider"_ gives an example on how to implement such a provider. This repository is an easy ready-to-use implementation of a _Value Set Provider_.
