Relators are not normally used directly in DdexMessages: Relators are Dictionary linking entities (or 'ontological entities') which are used to create all of the links which hold the Dictionary
structure together. Example: a relationship such as 'DealerPrice IsSubClassOf Price' results in a parent-child link being
established between 'Price' and 'DealerPrice'. Each Relator has a reverse or 'reciprocal' Relator which is used to describe the same relationship from the reverse point of view. Example: 'HasSubClass' is the reverse Relator of 'IsSubClassOf', and so a statement such as 'Price HasSubClass DealerPrice' has the same meaning as 'DealerPrice IsSubClassOf
Price'. This enables the Dictionary to be navigated in all directions. Some Relators (e.g., 'IsSameAs') are used for describing a relationship in both directions and so are their own reciprocals.
