| *<B>Assertion Description: </B> The <code>Query</code> ordering specification includes a list of one or more ordering declarations separated by commas. Each ordering declaration includes an expression whose type is one of: |
| <UL> |
| <LI>primitive types except <code>boolean</code></LI> |
| <LI>wrapper types except <code>Boolean</code></LI> |
| <LI><code>BigDecimal</code></LI> |
| <LI><code>BigInteger</code></LI> |
| <LI><code>String</code></LI> |
| <LI><code>Date</code></LI> |
| </UL> |
| followed by one of the following words: <code>"ascending</code>" or |
| *<code>"descending</code>" which indicates the ordering of the values for that expression. Ordering might be specified including navigation. The name of the field to be used in ordering via navigation through single-valued fields is specified by the Java language syntax of <code>field_name.field_name....field_name</code>. |
