    # that" approach is an artifact of the template oids changing as of

    # measures that were exported using previous versions of the MAT.

def extract_definition_from_template_or_type
  # Try to determine what kind of data criteria we are dealing with
  # First we look for a template id and if we find one just use the definition
  # status and negation associated with that
  # If no template id or not one we recognize then try to determine type from
  # the definition element.
  extract_definition_from_type unless extract_definition_from_template_id
end

#extract_definition_from_type ⇒ Object

Extract the definition (sometimes status, sometimes other elements) of the data criteria based on the type

  if @entry.at_xpath('./cda:grouperCriteria')
    @definition ||= 'derived'

  end
  # See if we can find a match for the entry definition value and status.
  entry_type = attr_val('./*/cda:definition/*/cda:id/@extension')
  handle_entry_type(entry_type)
end

#handle_entry_type(entry_type) ⇒ Object

Generate the definition and/or status from the entry type in most cases. If the entry type is nil, and the value is a specific occurrence, more parsing may be necessary.
