Content-type: application/xml; charset="iso-2022-kr"

   <?xml version="1.0" encoding="iso-2022-kr"?>

   This example shows application/xml with a Korean charset (e.g.,
   Hangul) encoded following the specification in [RFC-1557].  Since the
   charset parameter is provided, MIME and XML processors must treat the
   enclosed entity as encoded per [RFC-1557], independent of whether the
   XML entity has an internal encoding declaration (this example does
   show such a declaration, which agrees with the charset parameter).

   Since ISO-2022-KR has been defined to use only 7 bits of data, no
   content-transfer-encoding is necessary with any transport.

6.7 application/xml with Omitted Charset and UTF-16 XML Entity

   Content-type: application/xml

   {BOM}<?xml version='1.0'?>

   For this example, the XML entity begins with a BOM.  Since the
   charset has been omitted, a conforming XML processor follows the
   requirements of [REC-XML], section 4.3.3. Specifically, the XML
   processor reads the BOM, and thus knows deterministically that the
   charset encoding is UTF-16.

   An XML-unaware MIME processor should make no assumptions about the
   charset of the XML entity.

6.8 application/xml with Omitted Charset and UTF-8 Entity

   Content-type: application/xml

   <?xml version='1.0'?>

   In this example, the charset parameter has been omitted, and there is
   no BOM. Since there is no BOM, the XML processor follows the
   requirements in section 4.3.3, and optionally applies the mechanism
   described in appendix F (which is non-normative) of [REC-XML] to
   determine the charset encoding of UTF-8. The XML entity does not
   contain an encoding declaration, but since the encoding is UTF-8,
   this is still a conforming XML entity.

   An XML-unaware MIME processor should make no assumptions about the
   charset of the XML entity.

6.9 application/xml with Omitted Charset and Internal Encoding
    Declaration

   Content-type: application/xml

   <?xml version='1.0' encoding="ISO-10646-UCS-4"?>

   In this example, the charset parameter has been omitted, and there is
   no BOM.  However, the XML entity does have an encoding declaration
   inside the XML entity which specifies the entity's charset. Following
   the requirements in section 4.3.3, and optionally applying the
   mechanism described in appendix F (non-normative) of [REC-XML], the
   XML processor determines the charset encoding of the XML entity (in
   this example, UCS-4).

   An XML-unaware MIME processor should make no assumptions about the
   charset of the XML entity.
