/**
 * Test checking that adding an attribute correctly generates a
 * new namespace declaration if an equivalent namespace declaration exists but is masked.
 * The test attempts to create the following XML:
 *  * <a xmlns:p="urn:ns1">
 *   <b xmlns:p="urn:ns2">
 *     <c xmlns:p="urn:ns1" p:attr="test"/>
 *   </b>
 * </a>
 * It only explicitly creates the namespace declarations on <a> and
 * <b>. When adding the attribute to <c>, Axiom must generate
 * a new namespace declaration because the declaration on <a> is masked
 * by the one on <b>.
 * 
 * Note that because of WSTX-202, Axiom will not be able to serialize the resulting XML.
