Documentation

This is a "getter" TopicFunction that returns a list of known TopicTypes in a given web. Use it to create a selection in DataForms for the TopicType formfield. It adds the "none" type so that you can have (temporarily) un-typed topics. The type "TopicType" is added hardcoded so that you don't have to rely on that type being present in your web and to allow bootstrapping a type system in a web from scratch on as you will be able to create an initial TopicType TopicType this way.

Parameters

WEBS: list of webs to search for TopicTypes, defaults to BASEWEB
EXCLUDE: expression to exclude types (optional)
ADDITION: types that are listed additionally (optional)
