I replaced in my SiteMap.cs
this http://www.google.com/schemas/sitemap/0.84
with this http://www.sitemaps.org/schemas/sitemap/0.9
Today Google Webmaster tools give me an error in Sitemap

"The incorrect namespace
Your Sitemap or Sitemap index file namespace is not indicated correctly.
Your Sitemap or Sitemap index file does not properly declare the namespace. Expected: http://www.sitemaps.org/schemas/sitemap/0.9. Detected: http://www.sitemaps.org/schemas/sitemap/0.9/"

I checked my sitemap but is normal and correct (www.informarea.it/sitemap.axd)
What can be?
Can you help me?
Thanks
Fabrizio
