This interface is used for exposing settings of document converters to the user.
Assembly: Microsoft.SharePoint.Publishing (in Microsoft.SharePoint.Publishing.dll)
This interface is implemented by user controls that need to expose settings. The interface scope is specific to document converters in the context of the "Smart Client Authoring" feature. That is, the "document-to-publishing-page" conversion, as opposed to the "document-to-another-document" conversion.
