Interesting.  You're not actually quoting the full sentence:

	If the constant-expression is present, it shall be a converted
	constant expression of type stdâ::âsize_Ât and its value shall be
	greater than zero.

This suggests that:

	__u64 ptr[]

is actually valid since:

	D1 [ constant-expressionopt ] attribute-specifier-seqopt

suggests that the part between the brackets is optional.
