Class <<Type>> ControlledConcept (extends Definition )

Element to represent a defined concept.
A concept in the context of a GeologicVocabulary. A relationship class representing inclusion of an instance of a concept in a GeologicVocabulary. The GeologicConcept instance must have an associated definition (prototype 0..1), which may be text for human interpretation, or a formal description in the form of a geologic entity.

* items in the classification framework
* every GeologicUnit may be classified as being representative of a Controlled Concept. This may be a formal stratigraphic unit from a stratigraphic lexicon, or some generic mappable concept like 'alluvial fan deposit' or 'basaltic rock'.
* a Controlled Concept instance mayt be associated with one special feature or object, which is the prototype or normative description meant to specify what the concept represents.
