    This is a Endpoint resource
    Enum: "Endpoint"

  - `id` (string)
    Any combination of letters, numerals, "-" and ".", with a length limit of 64 characters.  (This might be an integer, an unprefixed OID, UUID or any other identifier pattern that meets these constraints.)  Ids are case-insensitive.

    May be used to represent additional information that is not part of the basic definition of the resource and that modifies the understanding of the element that contains it and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions.

Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).
