   1 Standard Unit Suffixes for Property names
   2
   3 Properties which have a unit of measure are recommended to have a unit
   4 suffix appended to the property name. The list below contains the
   5 recommended suffixes. Other variations exist in bindings, but should not
   6 be used in new bindings or added here. The inconsistency in the unit
   7 prefixes is due to selecting the most commonly used variants.
   8
   9 It is also recommended to use the units listed here and not add additional
  10 unit prefixes.
