Property for linking a term to a natural language meaning (a “Synset”) in Wordnet

xapi:closelyRelatedNaturalLanguageTerm while this is a sub property of skos:relatedMatch, it should only be used by the original vocabulary author. It relates a skos:Concept, such as any xAPI Verb, to a closely related wordnet:Synset — basically, a natural language meaning. All of the other properties in this section should only be used to relate xAPI terms of the same sort to each other — Verbs to Verbs, Activity Types to Activity Types, etc.
