Well, Brian, that's a good question.  As you may or may not be aware, XHTML is 
in many ways very similar to HTML.  Therefore, I assume to avoid combersome 
redundancy, the XHTML specification serves only to document the differences 
from HTML.  While the HTML 4.01 Strict DTD lists the acceptable values as 
"(GET|POST)", the specification states that the value is case-insensitive.  I 
suppose in XML attribute values listed in the DTD are case-sensitive such that 
you must use the case listed in the DTD.  That distinction should certainly be 
made abundantly clear in the XHTML documentation.  My question then is, will 
the user agent use the actual value of the attribute, or will it substitute the 
(correct) uppercase translation of the value in the HTTP request it sends?
