| 35 | elements that appear in the value list of permutation but in any order. It is applicable inside of <font face="Courier New" size="4"><b>record</b></font> <font face="Courier New" size="4"><b>of</b></font> | |
| 36 | templates or template fields only (i.e. within the pair of {}-s of the record of). | |
