The semantics of 'select' are essentially a flexible choice concept, in the general case, M from N, where M <= N. It initially seemed that 'select' would be a '1 from N' concept, in which case there was an idea that it might be used to make the choice semantics of single attributes with multiple children clearer, but this is not the case due to the more general 'N from M' meaning.{*}
