An explicitly specialized non-inline static data member or variable template specialization has ordered initialization.

Since English lacks a grouping operator it is unclear which adjectives apply to both sides of the "or". I initially read it as An (explicitly specialized non-inline static data member) or (variable template specialization), but I think it is supposed to be closer to An explicitly specialized non-inline (static data member or variable template specialization). Can this be rephrased to make this clear?

Maybe:

A non-inline static data member or variable template specialization has ordered initialization if it is explicitly specialized.

What about:

An explicit specialization of a non-inline static data member or of a variable template has ordered initialization.

Is it the explicit specialization that has ordered init, or the variable itself? Is there any difference?

Your suggestion says the specialization has ordered init. The original says the variable has ordered init.

A template is not a thing that could be initialized (it's not an object or reference; it's a template). Only a specialization of a (certain kind of) template can be initialized at all, irrespective of ordering.

Editorial meeting:
Suggestion: "A non-inline explicit specialization of a templated variable has ordered initialization."
Send e-mail to CWG reflector for heads-up. Apply after two weeks.
