bool PostProcessHasDependencies { get; }

Normally all post-process phases are executed concurrently after all process phases have completed. This also means that a post-process phase can access documents from the process phase of any pipeline (other than those with Isolated set to true) but not from the post-process phase in other pipelines. Sometimes it can be helpful for the post-process phase of a pipeline to itself have a dependency on the post-process phase of it's pipeline dependencies. Setting this to true will cause the post-process phase of this pipeline to wait to execute until all post-process phases of it's dependencies have completed, and will allow it to access documents from those post-process phases.
