cts:geospatial-json-property-child-reference( $property as xs:string, $child as xs:string, [$options as xs:string*] ) as cts:reference
Creates a reference to a geospatial json property child range index, for use as a
parameter to cts:value-tuples
cts:value-tuples
.
This function will throw an exception if the
specified range index does not exist.
precision
option takes precedence over
that implied by the governing coordinate system name, including the
value of the coordinate-system
option. For example, if the
governing coordinate system is "wgs84/double" and the precision
option is "float", then the reference uses single precision. An exception
is thrown if an index with the corresponding precision does not exist.
