> 	It is said in Section 3.3.1 of the CAP V1.0 specification
> that:
>
>      "Coordinates in the Southern and Western hemispheres
>       are signed negative with a leading dash."
>
> 	I am aware of no usage of the English language that permits
> one to refer to a "coordinate" as "negative." Coordinates are composed
> of pairs of numbers which represent latitude and longitude, any one or
> both of these numbers may be "negative." While the components of a
> coordinate may individually be "negative" (preceded by a "dash") a
> coordinate which contains such a "negative" component is not referred
> to as "negative" in normal English usage nor is such usage made in the
> realm of mathematics. (Is a coordinate with two "negative" components
> "negative" or "positive"?)
> 	When writing standards, it is best to use commonly accepted
> language and meanings in order to ensure that ambiguities do not
> result from misinterpretations.
