The values entered will be used by the client to provide the user with a workflow to be made available to the user for all of their documents.  The url should be a full path, such as 'http://localsharepointsite/Shared%20Documents'.  Some workflows require that the user sign a document with an in-document signature, workflows indicated as such will only be shown the the user as an option in applications that support in-document signatures. This workflow must also be made available on the document library (setting these values only lets the client know about the workflow).
