//! Group of multiple entities

/// Group of multiple entities
///
/// Represents a defined collection of entities that may be discussed or acted
/// upon collectively but which are not typically expected to act collectively.
/// These collections are also not typically formally or legally recognized.
/// NOTE: Group may be used to define families or households, which in some
/// circumstances may act collectively or have a degree of legal or formal
/// recognition. This should be considered an exception. When Group is used for
/// types of entities other than Patient or RelatedPerson, the expectation
/// remains that the Group will not act collectively or have formal recognition
/// \- use Organization if these behaviors are needed. For example, it is
/// possible for a 'family' Group to be a performer of an Observation or owner
/// of a Task. However, this is not permitted for a Group made up of
/// Practitioners, PractitionerRoles or Organizations. Organization or CareTeam
/// would need to be used instead. A Group of Practitioners could, however, be a
/// subject of an Observation.
