geo:coordinate-system-canonical(
   $name as xs:string,
   [$precision as xs:string]
) as xs:string

Summary

Get the canonical name for the coordinate system. An exception is thrown if no such coordinate system exists.

Usage Notes

The precision parameter takes precedence over any precision implicit in the coordinate system name. For example, if name is "wgs84/double" and precision is "float", then "wgs84" is returned.
