<para>persistance bits: bit 1 - keeps NS decl in properties of client connection
i.e stores the assignment in connection parameters so only the current connection will
see the namespace prefix declaration;
bit 2 - makes NS decl persistent, i.e. stores the declaration in global in-memory hashtable
as well as in a system table, loaded at server startup time, visible from all connections</para></refsect2>
