Source to Topic Matching
A topic may belong to several sources.
If no restrictions are defined, then all topics will be able to operate on all sources of the compatible type.
At request time, if a requested topic resolves to more than one source you must clarify
which source to operate on by using the sourceType and/or the sourceName parameters of the request.
The properties outlined below allow you to restrict which topics can operate on which source.
