Line 3234, Column 127: document type does not allow element "link" here
http://www.<MYDOMAIN.com/var/cache/_563a0f615810726ac1aabd5fd6575619.css" />
The element named above was found in a context where it is not allowed. This could mean that you have incorrectly nested elements -- such as a "style" element in the "body" section instead of inside "head" -- or two elements that overlap (which is not allowed).
One common cause for this error is the use of XHTML syntax in HTML documents. Due to HTML's rules of implicitly closed elements, this error can create cascading effects. For instance, using XHTML's "self-closing" tags for "meta" and "link" in the "head" section of a HTML document may cause the parser to infer the end of the "head" section and the beginning of the "body" section (where "link" and "meta" are not allowed; hence the reported error)
---------------------------------------
Line 3234 come just before the closing /body tag.
Line 3233 is "<script type="text/javascript" src="http://www.MYDOMAIN.com/var/cache/_095eb7bcf85d388ba7d7dc34fd64401a.js"></script>"
My question is where are these links normally called? They appear to be part of the "speed-up tool for Javascript" and "speed-up tool for CSS".
