I just ran a check on my site map using http://validator.w3.org it came up with the following:

Missing "charset" attribute for "text/xml" document.

The detected character encoding "us-ascii" has been suppressed and "utf-8" used instead.

No DOCTYPE found! Checking XML syntax only.

As a result of those errors(?) it said:

The document located at <https://www.fantasycostume.com/sitem...approducts.xml> was tentatively checked as XML. This means that with the use of some fallback or override mechanism, we successfully performed a formal validation of it. In other words, the document would validate as XML if you changed the markup to match the changes we have performed automatically, but it will not be valid until you make these changes. The parser implementations we used for this check are based on OpenSP (SGML/XML) and libxml2 (XML).

Can we get that info into the sitemap that Sitemap XML generates?
