A week ago (on April 4th), the W3C announced that XQuery 1.0, XPath 2.0, and XSLT 2.0 went into Last Call. Since this is the second Last Call, let me assure you that the intend of the working group is to make this the final one. The goal is still to get to recommendation within a year. One way to keep this going is that we request that people submit their comments by May 13th (and another one is that we discourage members of the WG to submit too many substantial comments).
Oleg has posted about the comparison of XQuery with PERL: Note that this was not sanctioned by the working group and the person who coined that comparison has received a fair number of email complaints from within and outside the working group. XQuery is really not comparable to PERL or vice versa :-).
In the following, I will list the documents, explain how to make comments and identify a few issues that I personally would like to see people provide feedback on the drafts.
