 The CodeQL library for C# analysis exposes the following extensible predicates:
 
 - ``sourceModel(namespace, type, subtypes, name, signature, ext, output, kind, provenance)``. This is used to model sources of potentially tainted data.
-- ``sinkModel(namespace, type, subtypes, name, signature, ext, input, kind, provenance)``. This is used to model sinks where tainted data maybe used in a way that makes the code vulnerable.

 - ``summaryModel(namespace, type, subtypes, name, signature, ext, input, output, kind, provenance)``. This is used to model flow through elements.
 - ``neutralModel(namespace, type, name, signature, kind, provenance)``. This is similar to a summary model but used to model the flow of values that have only a minor impact on the dataflow analysis.
