An XCSG ModelElement is either a node or edge in an XCSG graph.
All XCSG model elements have a source correspondence attribute, which indicates their origin.
XCSG model elements also have an id attribute, which uniquely identifies that element; the id attribute should enable those familiar with the analyzer which produced that node or edge to determine whether the graph already contains a node or edge representing a particular entity or relationship. No two model elements with equal IDs can exist in the same graph, to ensure each modeled element or relationship has a single representation in the graph.
