xml - Why is my sitemap file considered empty?

Question

I have a robots.txt file in the root of my site which has this one line in it:

Sitemap: http://www.awardwinnersonly.com/sitemap.xml

The sitemap.xml is also in the root of the site, and contains this text:

<?xml version="1.0" encoding="UTF-8"?>
-<urlset xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9 
http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">

    <priority>1.0</priority>
  </url>

      <changefreq>monthly</changefreq>
      <priority>.7</priority>
    </url>
</urlset>

Yet, after [re]publishing my site, and trying to navigate to http://www.awardwinnersonly.com/sitemap.xml, I get:

This page contains the following errors:

error on line 2 at column 1: Document is empty
Below is a rendering of the page up to the first error.

(nothing is shown below that - it is more-or-less a "white screen of death.")

What is wrong with either my xml file, robots file, or how I'm going about this?

Looks like a stray - got into your file.

$ curl -v http://www.awardwinnersonly.com/sitemap.xml
