Yes, compare <http://tools.ietf.org/html/rfc2045#section-5.1> on
the syntax of the MIME Content-Type header field:
 
| The type, subtype, and parameter names are not case sensitive.  For
| example, TEXT, Text, and TeXt are all equivalent top-level media
| types.  Parameter values are normally case sensitive, but sometimes

[...]

I'd be surprised if XHTML somehow managed to overrule HTTP and MIME
wrt http-equiv meta-elements.
