Example 7 in http://www.unicode.org/reports/tr14/#Examples
has these two rules NU × (NU | SY | IS) NU (NU | SY | IS)* × (NU | SY | IS | CL | CP )It appears to me that the first rule generates a subset of what the 2nd rule generates, and so is useless. It could be hence removed for simplicity, unless I'm missing something or there is a typo and it is meant to generate something else.
