[xacml] Operator mapping from XPath 2.0 Draft

I extracted type promotion and operator mapping from XPath 2.0 Draft 19
April 2002 Appendix B and created a PDF file. I removed operator
definitions relevant to duration and node. I left description "(missing)"
because the corresponding operator definition is useful for us (e.g. date
eq date).
