This document defines the "application/soap+xml" media type which can be used to describe SOAP 1.2 messages serialized as XML 1.0.
この文書は XML 1.0 で直列化した SOAP 1.2 メッセージを記述するために使用できる
application/soap+xml 媒体型を定義します。
SOAP version 1.2 (SOAP) is a lightweight protocol intended for exchange of structured information between peers in a decentralized, distributed environment. It defines an extensible messaging framework that contains a message construct based on XML technologies that can be exchanged over a variety of underlying protocols.
SOAP 1.2 版 (SOAP) は脱集中分散環境の同輩間の構造化情報の交換のための軽量プロトコルです。 SOAP は様々なプロトコルの上で交換できる XML 技術を基にしたメッセージ構造を含む、拡張可能なメッセージ付けの枠組みを定義しています。
This specification defines the media type "application/soap+xml" which can be used to identify SOAP 1.2 message envelopes that have been serialized with XML 1.0. Such serializations are useful as the basis of "wire formats" for SOAP 1.2 Protocol Binding Specifications [W3C.REC-soap12-part1-20030624], or in other situations where an XML serialization of a SOAP envelope is required.

The "application/soap+xml" media type explicitly identifies SOAP 1.2 message envelopes that have been serialised with XML 1.0; message envelopes with a different SOAP namespace version or using another XML serialisation MUST NOT use it.

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119].
- MIME media type name
- application
- MIME subtype name
- soap+xml
- Required parameters
- none
- Optional parameters
- "charset"
- This parameter has identical semantics to the charset parameter of the "application/xml" media type as specified in RFC 3023 [RFC3023].
- "action"
- This optional parameter can be used to specify the URI that identifies the intent of the message. In SOAP 1.2, it serves a similar purpose as the SOAPAction HTTP header field did in SOAP 1.1. Namely, its value identifies the intent of the message.
charsetapplication/xml 媒体型の charset
引数と同じ意味を持つ引数です。actionSOAPAction HTTP
頭欄と同様の目的で使います。つまり、値はメッセージの意図を識別します。The value of the action parameter is an absolute URI-reference as defined by RFC 2396 [RFC2396], which MUST be non-empty. SOAP places no restrictions on the specificity of the URI or that it is resolvable. Although the purpose of the action parameter is to indicate the intent of the SOAP message there is no mechanism for automatically computing the value based on the SOAP envelope. In other words, the value has to be determined out of band. It is recommended that the same value be used to identify sets of message types that are logically connected in some manner, for example part of the same "service". It is strongly RECOMMENDED that the URI be globally unique and stable over time.

action 引数の目的は SOAP メッセージの意図を示すことですが、
SOAP 封筒を基にして自動的に値を計算する仕組みはありません。

Use of the action parameter is OPTIONAL. SOAP Receivers MAY use it as a hint to optimize processing, but SHOULD NOT require its presence in order to operate.

- Encoding considerations
- Identical to those of "application/xml" as described in RFC 3023 [RFC3023], section 3.2, as applied to the SOAP envelope infoset.

- Security considerations
- Because SOAP can carry application defined data whose semantics is independent from that of any MIME wrapper (or context within which the MIME wrapper is used), one should not expect to be able to understand the semantics of the SOAP message based on the semantics of the MIME wrapper alone. Therefore, whenever using the "application/soap+xml" media type, it is strongly RECOMMENDED that the security implications of the context within which the SOAP message is used is fully understood. The security implications are likely to involve both the specific SOAP binding to an underlying protocol as well as the application-defined semantics of the data carried in the SOAP message (though one must be careful when doing this, as discussed in SOAP 1.2 Part 1 [W3C.REC-soap12-part1-20030624], section Binding to Application-Specific Protocols).
SOAP はその意味が MIME 覆い子のもの
(や MIME 覆い子が使用されている文脈) から独立した応用定義のデータを伝達できますから、
MIME 覆い子だけの意味に基づいて SOAP メッセージの意味を理解できると期待するべきではありません。
従って、 application/soap+xml 媒体型を使う時は常に SOAP
メッセージが使われている文脈による安全性への影響を完全に理解することを強く推奨します。
安全性への影響は特定の下位プロトコルへの束縛にも、

Also, see SOAP 1.2 Part 1 [W3C.REC-soap12-part1-20030624], the entire section Security Considerations.
また、 SOAP 1.2 第1部の安全性に関してもご覧下さい。
In addition, as this media type uses the "+xml" convention, it shares the same security considerations as described in RFC 3023 [RFC3023], section 10.
加えて、この媒体型は +xml 記法を使っていますから、
RFC 3023 10章で説明されている安全性についての考察も該当します。
The action parameter is not a security mechanism, and SHOULD NOT be used for authentication. If the action parameter is used to make decisions (e.g., dispatch, filtering), it is RECOMMENDED that the basis for such decisions should be confirmed by examining the SOAP Envelope.
