Question about XPath 2.0

[Murali Mani <mani@CS.UCLA.EDU>]

Hi,

I was just glancing at XPath 2.0 (after a long time !!), I find a
"ForExpr" as part of XPath 2.0.  This was surprising, can you provide me a
reasoning behind this?

My reasoning: I was under the impression that XPath will provide
expressions that will allow us to get nodes and values from XML documents,
I thought this will be serve as the basis for most operations on XML. I
felt XQuery/XSLT etc can sit on top of XPath.

Now why do we need to include ForExpr etc, and allow us more than the
basic necessities, for example, now we can construct elements etc? Any
opinions?

thanks and regards - murali.
