Nice-to-have: validate that an element has one or more attributes in a given list. Similar to mandatory_oneof: "['foo', 'bar']" but would allow both attributes foo and bar to exist.
Name suggestions: mandatory_atleastoneof, mandatory_oneoformore
Current workaround is to duplicate the tag spec. Context: https://github.com/ampproject/amphtml/issues/12372#issuecomment-372814132
How about: mandatory_anyof
