The Content Creator may provide a style sheet allowing selection of different views, or multiple style sheets in order for a Content Consumer to achieve optimal display, or it may rely upon the Content Consumer’s rendering of the style attributes. 

A Content Consumer that implements the Narrative Formatting Option uses document style values to provide different views of a document. If multiple style sheets have been supplied for a document by a Content Creator, the Content Consumer allows the user to select from the set of alternates to change the view of the document.
