Example 75 with SynapseException

/**
 * Add the namespace declarations of a given {@link OMElement} to the namespace
 * context of an XPath expression. Typically this method is used with an XPath
 * expression appearing in an attribute of the given element.
 * <p>
 * Note that the default namespace is explicitly excluded and not added to the
 * namespace context. This implies that XPath expressions
 * appearing in Synapse configuration files follow the same rule as in XSL
 * stylesheets. Indeed, the XSLT specification defines the namespace context of
 * an XPath expression as follows:
 * <blockquote>
 * 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
 * </blockquote>
 *
 * @param xpath
 * @param elem
 * @param log
