Where are the bitwise operators ?

	Dear sirs,

	We have been observing the XPath drafts, and in fact it is very
powerful. But our group, and many other friends are missing the common
"bitwise" operators: and, or, xor, not. Is there any particular reason
why it is not been delivered for the next version of XPath (2.0)?

	Yours sincerely,

	Vinicius Bloise.
