Elements

Necessary for support of the intergeo_elements symbols is that a symbol can be interpreted as a concrete instance of a certain type of mathematical object and that a visualization of this instance can be made. Also, an instance of such an object within the software must be available to be exported to (an) OpenMath (compatible) representation of the instance. The parsing of abstract relations to other objects is not necessary for this level of conformance.
