While going through the exercise of updating the old profile vocab JSON, I noticed the closelyRelatedNaturalLanguageTerm was left out of the profile spec? I still see some value in providing this for verbs, activity types, etc. for machine understanding of terms that may have multiple meanings.

This property is used to connect the xAPI term to a specific sense, or meaning, in natural language that is very closely related with a wordnet definition. Wordnet aids in word sense disambiguation, and can be used with many different languages.

Is there a strong objection to leaving these in profiles? A lot of time was spent referencing wordnet for word sense disambiguation.
