var geo = require("/MarkLogic/geospatial/geospatial");

geo.linestringConcat([
  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 equivalent to the following WKT:
    LINESTRING(1 1,2 2,3 3,4 4,5 5)
