def apply(values: Iterable[URI], moreValues: Iterable[URI]*): Ns with Attr

Match one or more Iterables of attribute values.

Match one or more Iterables of attribute values.

Multiple Iterables are concatenated into one Iterable of values to be matched.

Applying value(s) to an attribute has different semantics depending on what operation is performed:
