Required attributes:
base_url - the top-level URL of the site being mapp
But when GSiteCrawler creates a sitemap.xml there is no section < Site
base_url="http://xxx.com/". in the xml file. I would like to know if
this is causing the issue
I do have a section <url><loc>http://www.xxx.com/</loc>.... just after
the begining of the <urlset ...> and this seems to be where google is
reporting the http error
