Example
xquery version "1.0-ml";
import module namespace geo = "http://marklogic.com/geospatial"
at "/MarkLogic/geospatial/geospatial.xqy";
geo:linestring-concat((
cts:linestring((cts:point(1,1),cts:point(2,2),cts:point(3,3))),
cts:linestring((cts:point(3,3),cts:point(4,4),cts:point(5,5)))
))
==> A cts:linestring similar to the following:
cts:linestring("LINESTRING(1 1,2 2,3 3,4 4,5 5)")
