  <p>
  The content-encoding property is used as a modifier to the content-type. When present, its value
  indicates what additional content encodings have been applied to the application-data, and thus what
  decoding mechanisms need to be applied in order to obtain the media-type referenced by the content-type
  header field.
  <p>
  Content-encoding is primarily used to allow a document to be compressed without losing the identity of
  its underlying content type.
  <p>
  Content-encodings are to be interpreted as per section 3.5 of RFC 2616 [RFC2616]. Valid content-encodings
  are registered at IANA [IANAHTTPPARAMS].
  <p>
  The content-encoding MUST NOT be set when the application-data section is other than data. The binary
  representation of all other application-data section types is defined completely in terms of the AMQP
  type system.
  <p>
  Implementations MUST NOT use the identity encoding. Instead, implementations SHOULD NOT set this property.
  Implementations SHOULD NOT use the compress encoding, except as to remain compatible with messages originally
  sent with other protocols, e.g. HTTP or SMTP.
  <p>
  Implementations SHOULD NOT specify multiple content-encoding values except as to be compatible with messages
  originally sent with other protocols, e.g. HTTP or SMTP.
