According to the data in 14.0.0 ucd this defines a subset of the ID line breaking class, that makes it easy for me to support the rule by splitting the ID class internally. 

But is that guaranteed to hold in the future ? Could we maybe have a proper line breaking class for it in subsquent versions ?
