docs: Does a lookup if the given property data type has an associated translator
  available.
  <p>
  The translator looked for is specified in the property map. An available translator
  is implemented and can be used for translation.
  
  @param dataType property data type to lookup
  @return <code>true</code> iff translator and its subtype was found,
  <code>false</code> otherwise
