Unfortunately, ABNF defines that strings enclosed in double quotes are case-insensitive, see http://tools.ietf.org/html/rfc5234#section-2.3, and doesn't provide a means for literally stating case-insensitive strings

So our rules would have to look like

primitiveTypeName = [  %x45.64.6d "." ] ; Edm.
                                       ( %x42.69.6e.61.72.79  ; Binary
                                       / ...
                                       )

A better way is to define (in prose) at the top of the ABNF file that string literals enclosed in single quotes are case-sensitive.

If we go for case-sensitivity, I'd prefer the CamelCase names used in section 3.5 of the CSDL specification.

> The current ABNF defines the Edm primitive type names case-insensitive, yet all examples use Edm.Binary etc.
> As they only appear within null'Xxx', isof() and cast() expressions, case doesn't matter as long as we reserve the "Edm" namespace in all case variants.
