/// combination of ','(and), '|'(or), and '()'. By default, the priority of
/// ',' is higher than that of '|' .
/// E.g:
/// A,B|C means the builtin function requires both A and B, or C.
/// If we want the builtin function requires both A and B, or both A and C,
/// there are two ways: A,B|A,C or A,(B|C).
/// The FeaturesList should not contain spaces, and brackets must appear in
/// pairs.
