Parameters are a generic form of data storage within elements. The parameters are visible through the Autodesk Revit user interface in the Element Properties dialog. This method is used to retrieve a parameter for a known shared parameter. When a shared parameter is created it is assigned a Guid which will not change. This guid can be used to retrieve the piece of data from the element at a later time.
