I note with no little sense of irony that the W3C has finally ratified XQuery 1.0 and its related standards such as XPath 2.0 and XSLT 2.0. I guess that when we wrote Early Adopter XQuery back in 2001, the bleeding edge was less a flowing vein and more a vague sense that there was some beetroot juice on the edge of a knife in the general vicinity.
