Overview

If you add a method, keep in mind two things: (1) the first argument will always be a list of nodes from which to filter. In the case of context methods (such as position), the function should return an array with a value for each child in the array. (2) all method calls from XML will have "-" replaced with "_". Therefore, in XML, "local-name()" is identical (and actually becomes) "local_name()"
