> Due to complexity of propagating the fix through the framework, it might be worth to
update org/apache/camel/builder/xml/XPathBuilder.java:1218 to instantiate net.sf.saxon.xpath.XPathFactoryImpl
directly, especially considering Saxon manual starting from version 9.7 explicitly says not
to consider them a provider of javax.xml.xpath.XPathFactory (http://www.saxonica.com/html/documentation/xpath-api/jaxp-xpath/factory.html)
