value of attribute "dir" cannot be "LTR"; must be one of "ltr", "rtl".

If the specification says that the value is case-insensitive, then all implementations have to do a case insensitive match. If not, implementations can choose if they support the case insensitive values of "ltr" and "rtl", while the specification allows "ltr" and "rtl" only.

Is it good to allow the value to be case-insensitive? In XHTML, the value is matched case-sensitively.

This is not true for (at least) XHTML5, and implementations of XHTML in Opera and Firefox. Demo used:

data:text/xml,<html xmlns='http://www.w3.org/1999/xhtml' dir='RTL'>test</html>
