For interoperability, "ltr" and "rtl" in all lowercase should be the best.
The specification should not say that implementations are allowed to differ,
but it cannot control the real situation. Programmers still can decide how
their programs handle the values, even though the spec. said "MUST NOT".

value of attribute "dir" cannot be "LTR"; must be one of "ltr", "rtl".
I didn't claim anything about XHTML 1.x.
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.
It doesn't help interoperability if implementation are allowed to differ.
