(published in RFC 3023 in January 2001, last updated 2014-04-17 via RFC7303) Type name: text Subtype name: xml-external-parsed-entity Required parameters: none Optional parameters: charset See Section 3 of RFC7303. Encoding considerations: Same as for application/xml (Section 9.1 of RFC7303). Security considerations: See Section 10 of RFC7303. Interoperability considerations: XML external parsed entities are as interoperable as XML documents, though they have a less tightly constrained structure and therefore need to be referenced by XML documents for proper handling by XML processors. Similarly, XML documents cannot be reliably used as external parsed entities because external parsed entities are prohibited from having standalone document declarations or DTDs. Identifying XML external parsed entities with their own content type enhances interoperability of both XML documents and XML external parsed entities.
