Please refer to the attached figure.

Example :
 
<Map_Declination>
  <GRID_DECLINATION unit='DMS'>5300</GRID_DECLINATION>
  <MAGNETIC_DECLINATION unit='DMS'>-43600</MAGNETIC_DECLINATION>
  <MAGNETIC_DECLINATION_DATE>1984-01-01</MAGNETIC_DECLINATION_DATE>
  <MAGNETIC_DECL_ANNUAL_CHANGE unit='DMS'>840</MAGNETIC_DECL_ANNUAL_CHANGE>
</Map_Declination>
