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