org.apache.axiom.om.xpath.AXIOMXPath.addNamespaces()
Add the namespace declarations of a given {@link OMElement} to the namespacecontext of an XPath expression. Typically this method is used with an XPath expression appearing in an attribute of the given element.
Note that the default namespace is explicitly excluded and not added to the namespace context. This makes the behaviour of this method consistent with the rules followed in XSL stylesheets. Indeed, the XSLT specification defines the namespace context of an XPath expression as follows:
the set of namespace declarations are those in scope on the element which has the attribute in which the expression occurs; [...] the default namespace (as declared by xmlns) is not part of this set
@param element the element to retrieve the namespace context from @throws JaxenException if an error occurred when adding the namespace declarations

            AXIOMXPath xpath = new AXIOMXPath(xpathString);
            // here if user has given prefix namespace mappings
            // we use it. otherwise get from the om element existing
            // mappings
            if ((namespacePrefixes == null) || namespacePrefixes.isEmpty()) {
                xpath.addNamespaces(eventOMElement);
            } else {
                for(XpathDefinition xpathDefinition : namespacePrefixes){
                    xpath.addNamespace(xpathDefinition.getPrefix(),xpathDefinition.getNamespace());
                }
