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, the source to operate on must be clarified by using the sourceType and/or the sourceName parameters of the request. The properties outlined below restrict which topics can operate on which source.
