For each concept XML element contained by a codeSystem XML element, the LexEVS loader will create a LexGrid Entity (A5) and a "hasSubtype" association (A4) with the respective LexGrid Entity (A3) representing the codeSystem where the codeSystem entity (A3) is the source entity and the concept entity (A5) is the target entity..  The LexGrid Entity representing a concept XML element will have its entityCode value comprised of the code attribute value of the code XML element contained by the concept XML element and the value of the conceptProperty XML element contained by the concept XML element where the conceptProperty element has a type attribute value defined as the concept's internal identifier type ("internalId").  These two values are concatenated with the colon (":") character to create the entityCode value of the LexGrid Entity as depicted by the value "A:19960" under A5.

Concepts having concept relationships with other concepts will be created by the LexEVS loader such the association's name (or association predicate) will be the relationshipName attribute value of the conceptRelationship XML element in the load source file.  NOTE:  these associations between concepts are not depicted in the above image.
