| *<B>Assertion Description: </B> |
| If an implementation supports nontransactional read, then a call to |
| <code>Transaction.setNontransactionalRead</code> with a parameter value of |
| <code>true</code> will set the flag to <code>true</code> and allows persistent |
| instances to be read outside of a transaction. |
| Queries and navigation will be allowed without an active transaction. |
