Compliant as of SFSQL 1.1.  I'm not sure what OGC are going to do for
compliance testing for 1.2, since they haven't updated their test
suite.

Unless you actually run the databases and try them in detail, your
study will be pretty sterile. I have seen a large number of these and
they all consist of trolling the documentation and rarely testing the
actual functionality.

Want to do something interesting? See what Oracle Spatial does when
you run the tests in the JTS test suite through it.
