  /**
   * There might be multiple mappings per propery name, like <code>gml:name[1] = att1</code>, <code>
   * gml:name2 = strConcat(att2, att3)</code>, <code>gml:name[3] = "sampleValue</code>.
   *
   * <p>In the BoreHole test mapping used here, the following mappings exist for gml:name:
   *
   * <ul>
   *   <li>gml:name[1] = strConcat( strConcat(QS, strConcat("/", RT)), strConcat(strConcat("/",
   *       NUMB), strConcat("/", BSUFF)) )
   *   <li>gml:name[2] = BGS_ID
   *   <li>gml:name[3] = NAME
   *   <li>gml:name[4] = ORIGINAL_N
   * </ul>
   *
   * This means the "unrolled" filter for <code>gml:name = "SWADLINCOTE"</code> should be <code>
   * strConcat( strConcat(QS, ...) = "SWADLINCOTE"
