====GML Simple Features Profile====

The ''GML Simple Features Profile'' is a more complete profile of GML than the above ''Point Profile'' and supports a wide range of vector feature objects, including the following:

# A reduced geometry model allowing 0d, 1d and 2d linear geometric objects (all based on linear interpolation) and the corresponding aggregate geometries (gml:MultiPoint, gml:MultiCurve, etc.).
# A simplified feature model which can only be one level deep (in the general GML model, arbitrary nesting of features and feature properties is not permitted).
# All non-geometric properties must be XML Schema simple types – i.e. cannot contain nested elements.
# Remote property value references (xlink:href) just like in the main GML specification.

Since the profile aims to provide a simple entry point, it does not provide support for the following:
* coverages
* topology
* observations
* value objects (for real time sensor data)
* dynamic features

Nonetheless it supports a good variety of real world problems.
