doesn't work because you can specify conditionnal expression only into predicate,
between '[' and ']'
like this

/data/stuff/child::*[self::a or self::b]
or
/data/stuff/child::*[name()='a' or name()='b']
or
/data/stuff/*[self::a or self::b]

With absolute paths, I think you can't write a shorter expression
