yes it's a bit odd really that the let clause of FLWOR didn't
survive into XPath's For expression.
Some people wanted less of the FLWOR expression to make into XPath, some
wanted more. As often happens, the compromise that ended up in the spec was
agreed early on, and never changed because there was never a majority in
favour of any proposal to change it.
I think it's also an odd omission that XPath has no sorting capability,
though I'm glad the XQuery "order by", with its strange tuple-based
semantics, didn't make it in.
