! !DESCRIPTION:
!   \label{api:DynamicMaskSetR4R4R4}
!   Set an {\tt ESMF\_DynamicMask} object suitable for 
!   destination element typekind {\tt ESMF\_TYPEKIND\_R4},
!   factor typekind {\tt ESMF\_TYPEKIND\_R4}, and
!   source element typekind {\tt ESMF\_TYPEKIND\_R4}.
!   
!   All values in {\tt dynamicMask} will be reset by this call.
!
!   See section \ref{RH:DynMask} for a general discussion of dynamic masking.
!
!   The arguments are:
!   \begin{description}
!   \item[dynamicMask] 
!     DynamicMask object.
!   \item [dynamicMaskRoutine]
!     The routine responsible for handling dynamically masked source and 
!     destination elements. See section \ref{RH:DynMask} for the precise
!     definition of the {\tt dynamicMaskRoutine} procedure interface.
!     The routine is only called on PETs where {\em at least one} interpolation 
!     element is identified for special handling.
!   \item [{[handleAllElements]}]
!     If set to {\tt .true.}, all local elements, regardless of their dynamic
!     masking status, are made available to {\tt dynamicMaskRoutine} for
!     handling. This option can be used to implement fully customized
!     interpolations based on the information provided by ESMF.
!     The default is {\tt .false.}, meaning that only elements affected by
!     dynamic masking will be handed to {\tt dynamicMaskRoutine}.
!   \item [{[dynamicSrcMaskValue]}]
!     The value for which a source element is considered dynamically
!     masked.
!     The default is to {\em not} consider any source elements as
!     dynamically masked.
!   \item [{[dynamicDstMaskValue]}]
!     The value for which a destination element is considered dynamically
!     masked.
!     The default is to {\em not} consider any destination elements as
!     dynamically masked.
!   \item[{[rc]}] 
!     Return code; equals {\tt ESMF\_SUCCESS} if there are no errors.
!   \end{description}
