Re: [xml-dev] XPath and a continuous, uniform information space

Oh Michael, this is music in my ears!

As I love the XPath syntax and am dismayed at the way how JSONiq replaces XPath by FLWOR when it comes to dealing with JSON - that is, replaces path syntax by SQL-like constructs.

Syntax is very important.

What is the semantic difference between an axis and a function call

It's largely syntax.

Don't underestimate the importance of syntax!

There's a lot of difference in usability between

$customer/order[paid=false()]/product/price

and

for $c in $customer for $o in orders($c) for $p in products($o) where not(paid($o)) return price($p)
