I think the definitions should add "using the SRS of geom".
I thought that GeometryCollection can have several SRS, but then found this in sf_geometries.ttl: "All the elements in a GeometryCollection shall be in the same Spatial Reference System. This is also the Spatial Reference System for the GeometryCollection."
So the definitions could also add "(every geometry, even GeometryCollection, has a single SRS)"
The functions
(min|max)(X|Y|Z)
https://opengeospatial.github.io/ogc-geosparql/geosparql13/document.html#_function_geofmaxx are defined as "returns the maximum X coordinate for geom" and declared to returnxsd:double
