I am looking for feedback on the XQuery programming language. Please answer all questions as completely as possible. This poll and other information is forming the basis of a talk I am giving at GOTO 2011 Arhus, Denmark (http://lanyrd.com/2011/gotocon-aarhus/shqhc/). I will share all results at the end of October 2011.
Please help Jim Fuller out with his survey on XQuery!
