Note 1

Reading and direct transformation of GML data conforming to the Simple Features Profile conformance level Zero, and Simple Feature Collections in version 3.1.1 (support for 2.1.2 coming soon) is supported. The writer always writes to the Simple Features Profile. There is no firm limit to the size of file that can be read into the Viewer in Geographic Calculator, but if the GML file has coordinate lists exceeding one million characters, the odds of display issues will increase.
