Title: RE: [xacml] Operator mapping from XPath 2.0 Draft

How do you propose to map type "numeric"?

In general, I am rather concerned that no clear type compatibility/conversion 

rules are defined. It is not just hard to write an implementation, even with an

unlimited supply of summer interns avaialable, it is unsafe  - different

implementation are bound to  interpret it just different enough to cause a lot

of problems.

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).
