<title>PostGIS Function Support Matrix</title>\r
\r
<para>Below is an alphabetical listing of spatial specific functions in PostGIS and the kinds of spatial\r
- types they work with.</para>\r
+ types they work with or OGC/SQL compliance they try to conform to.</para>\r
<para>A + means the function works with the type or subtype natively. A T means it works but has a transform cast built-in to \r
cast to geometry, transform and then cast back. A * means the function works with it, but only does because of auto-casting\r
behavior.</para>\r
