      The implementation of the query parameter classes seems incomplete and there needs to be follow up with the author
      of the query interface classes for the best approach. Right now, it seems like using the where filter is the only
      way to handle this conversion. However, it seems like this functionality should be abstracted into a module that
      handles operations related to the object-builder naming scheme. There is an additional issue where conversion
      from the element name / entity path to the name field in the query parameter objects requires going through
      StructuredLinkableSpecName.
  
      TODO: Replace this method once ideal implementations are in place.
