`static double` `ExsltDynamic.max(ExpressionContext myContext, NodeList nl, java.lang.String expr)` The dyn:max function calculates the maximum value for the nodes passed as the first argument, where the value of each node is calculated dynamically using an XPath expression passed as a string as the second argument.

`static NodeList` `ExsltDynamic.map(ExpressionContext myContext, NodeList nl, java.lang.String expr)` The dyn:map function evaluates the expression passed as the second argument for each of the nodes passed as the first argument, and returns a node set of those values.
`static XObject` `ExsltDynamic.evaluate(ExpressionContext myContext, java.lang.String xpathExpr)` The dyn:evaluate function evaluates a string as an XPath expression and returns the resulting value, which might be a boolean, number, string, node set, result tree fragment or external object.
`static NodeList` `ExsltDynamic.closure(ExpressionContext myContext, NodeList nl, java.lang.String expr)` The dyn:closure function creates a node set resulting from transitive closure of evaluating the expression passed as the second argument on each of the nodes passed as the first argument, then on the node set resulting from that and so on until no more nodes are found.
