Output transformations pipelines for wikitext The classes in the `Stages/` subdirectory contains HTML and DOM transforms for use in output processing pipelines, i.e. postprocessors for `ParserOutput` objects that either directly result from a parse or are fetched from `ParserCache`. The default pipeline is created by `DefaultOutputTransformFactory`; it corresponds to what was previously contained in `ParserOutput::getText`. The `shouldRun` method in these stages uses defaults that indicates if the stage runs or not in the default `OutputTransformPipeline`.
