 * Abstract Base Class
 *
 * @remarks
 * Base Type: Base definition for all types defined in FHIR type system.
 *
 * The Base type that all other types specialize.
 * This type has no properties or constraints.
 * This class contains abstract methods useful to all FHIR classes.
 *
 * **FHIR Specification**
 * - **Short**: Base for all types and resources
 * - **Definition**: Base definition for all types defined in FHIR type system.
 * - **FHIR Version**: 5.0.0; Normative since 4.0.0
 *
 * @privateRemarks
 * Loosely based on HAPI FHIR org.hl7.fhir-core.r4.model.Base
 *
 * @category Base Models
 * @see [FHIR Base](http://hl7.org/fhir/StructureDefinition/Base)
