java.lang.Object	evalWithTrace(org.w3c.dom.Node contextNode, XPathExpr expr, org.w3c.dom.Node namespaceNode, org.w3c.dom.NodeList contextList, LookupResult result) returns also all the referenced nodes, used by XForms Calculation engine and dynamic UI dependencies
ModelContext	getModelContext()
XFormsContext	getXFormsContext()
boolean	hasFunction(java.lang.String uri, java.lang.String funcName) for model/@function processing, checks whether this function exists
void	setContext(XFormsContext handler, ModelContext mcontext) set the evaluation context and default context node if context node is null later
