    /**
     * Siren entity.
     *
     * @param sirenClasses
     *         Describes the nature of an entity's content based on the current representation. Possible values are
     *         implementation-dependent and should be documented. MUST be an array of strings. Optional.
     * @param properties
     *         A set of key-value pairs that describe the state of an entity. In JSON Siren, this is an object such as
     *         <code>{ "name": "Kevin", "age": 30 }</code>. Optional.
     * @param entities
     *         A collection of related sub-entities. If a sub-entity contains an href value, it should be treated as an
     *         embedded link. Clients may choose to optimistically load embedded links. If no href value exists, the
     *         sub-entity is an embedded entity representation that contains all the characteristics of a typical
     *         entity. One difference is that a sub-entity MUST contain a rel attribute to describe its relationship to
     *         the parent entity. In JSON Siren, this is represented as an array. Optional.
     * @param links
     *         A collection of items that describe navigational links, distinct from entity relationships. Link items
     *         should contain a rel attribute to describe the relationship and an href attribute to point to the target
     *         URI. Entities should include a link rel to self. In JSON Siren, this is represented as "links": [{
     *         "rel":
     *         ["self"], "href": "http://api.x.io/orders/1234" }] Optional.
     * @param actions
     *         A collection of action objects, represented in JSON Siren as an array such as { "actions": [{ ... }] }.
     *         See Actions. Optional
     * @param rels
     *         Defines the relationship of the sub-entity to its parent, per Web Linking (RFC5899). MUST be an array of
     *         strings. Required.
     * @param title
     *         Descriptive text about the entity. Optional.
