/**
 * The entity element declares an entity bean. The declaration consists of: an optional description; optional display name; optional small icon file name; optional large icon file name; a unique name assigned to the enterprise bean in the deployment descriptor; the names of the entity bean's home and remote interfaces, if any; the names of the entity bean's local home and local interface, if any; the entity bean's implementation class; the entity bean's persistence management type; the entity bean's primary key class name; an indication of the entity bean's reentrancy; an optional specification of the entity bean's cmp-version; an optional specification of the entity bean's abstract schema name; an optional list of container-managed fields; an optional specification of the primary key field; an optional declaration of the bean's environment entries; an optional declaration of the bean's EJB references; an optional declaration of the bean's local EJB references; an optional declaration of the security role references; an optional declaration of the security identity to be used for the execution of the bean's methods; an optional declaration of the bean's resource manager connection factory references; an optional declaration of the bean's resource environment references; an optional set of query declarations for finder and select methods for an entity bean with cmp-version 2.x.
 * The optional abstract-schema-name element must be specified for an entity bean with container managed persistence and cmp-version 2.x. The optional primkey-field may be present in the descriptor if the entity's persistence-type is Container. The optional cmp-version element may be present in the descriptor if the entity's persistence-type is Container. If the persistence-type is Container and the cmp-version element is not specified, its value defaults to 2.x.
 * The optional home and remote elements must be specified if the entity bean cmp-version is 1.x.
 * The optional local-home and local elements must be specified if the entity bean has a local home and local interface.
 * The optional query elements must be present if the persistence-type is Container and the cmp-version is 2.x and query methods other than findByPrimaryKey have been defined for the entity bean.
 * The other elements that are optional are "optional" in the sense that they are omitted if the lists represented by them are empty. At least one cmp-field element must be present in the descriptor if
 * the entity's persistence-type is Container and the cmp-version is 1.x, and none must not be present if the entity's persistence-type is Bean.
