  READ or WRITE transactions start in that state and do not change for the
  lifetime of the transaction.
  <ul>

  <li><code>WRITE</code>: this guarantees a WRITE will complete if <code>commit()</code> is
  called. The same as <code>begin(ReadWrite.WRITE)</code>.

  <li><code>READ</code>: the transaction can not promote to WRITE,ensuring read-only
  access to the data. The same as <code>begin(ReadWrite.READ)</code>.

  <li><code>READ_PROMOTE</code>: the transaction will go from "read" to "write" if an
  update is attempted and if the dataset has not been changed by another write
  transaction. See also <a href="Transactional.html#promote()"><code>Transactional.promote()</code></a>.

  <li><code>READ_COMMITTED_PROMOTE</code>: Use this with care. The promotion will
  succeed but changes from other transactions become visible.

  </ul>

  Read committed: at the point transaction attempts promotion from "read" to
  "write", the system checks if the dataset has change since the transaction started
  (called <code>begin</code>). If <code>READ_PROMOTE</code>, the dataset must not have
  changed; if <code>READ_COMMITTED_PROMOTE</code> any intermediate changes are
  visible but the application can not assume any data it has read in the
  transaction is the same as it was at the point the transaction started.

  This operation is optional and some implementations may throw
  a <a href="../JenaTransactionException.html" title="class in org.apache.jena.sparql"><code>JenaTransactionException</code></a> exception for some or all <a href="../../query/TxnType.html" title="enum class in org.apache.jena.query"><code>TxnType</code></a> values.
