Agree fully.  I was assuming (checking again now) that the case was
specified in the spec.

The 'z' in timestamps is specified as such, at least the explanation
and all examples show lower-case.  The spec often specifies a
character between '' characters, and there's no example of a capital
'Z'.  There's no explicit statement that a 'Z' may not be used.

Same for N/S/E/W:  The explanations and all examples use capitals,
but it is never explicitly stated that lower-case not be used.
