Converted to Monticello package.
NOTE: Be aware that in order to distribute a modification to XMLNode (from YAXO, I believe), the category of XMLNode has been modified in this package to XPath-XML. Consequently the full definition for this class (with all methods) has been included in this package, even though the only requirements are 1 additional instance variable, 2 accessor methods, and modifications to 3 existing methods to support the new variable. I hope to make this package friendlier to other packages in the future.
