XQuery Survey 2011

I am looking for feedback on the XQuery programming language to incorporate into a wider analysis of the language. Please answer all questions as completely as possible.

This poll and other information will be the basis of a talk I am giving about XQuery at GOTO 2011 Arhus , Denmark (http://lanyrd.com/2011/gotocon-aarhus/shqhc/).

This survey will close on Oct 1st, 2011 and the results of this query and subsequent analysis will be released at the end of October.

Thank you. Jim Fuller
