(Non-Normative)
This specification describes the use of the X.509
authentication framework with the Web Services Security:
An X.509 certificate specifies a binding between a public key and a set of attributes that includes (at least) a subject name, issuer name, serial number and validity interval. This binding may be subject to subsequent revocation advertised by mechanisms that include issuance of CRLs, OCSP tokens or mechanisms that are outside the X.509 framework, such as XKMS.
An X.509 certificate may be used to validate a public key that may be used to authenticate a SOAP message or to identify the public key with SOAP message that has been encrypted.
Note that Sections 2.1, 2.2, all of 3, and indicated parts of 5 are normative. All other sections are non-normative.
2
Notations and
Terminology (Normative)
This section specifies the notations, namespaces and terminology used in this specification.
2.1 Notational
Conventions
The keywords "MUST", "MUST NOT",
"REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "
When describing abstract data models, this specification uses the notational convention used by the XML Infoset. Specifically, abstract property names always appear in square brackets (e.g., [some property]).
When describing concrete XML schemas, this specification
uses a convention where each member of an element’s [children] or [attributes]
property is described using an XPath-like notation (e.g., /x:MyHeader/x:SomeProperty/@value1). The use of {any} indicates the presence of an
element wildcard (<xs:any/>). The use of @{any} indicates the presence of
an attribute wildcard (<xs:anyAttribute/>).
2.2 Namespaces
Namespace URIs (of the general form "some-URI") represents some application-dependent or context-dependent URI as defined in RFC 3986 [URI]. This specification is designed to work with the general SOAP [SOAP11, SOAP12] message structure and message processing model, and should be applicable to any version of SOAP. The current SOAP 1.1 namespace URI is used herein to provide detailed examples, but there is no intention to limit the applicability of this specification to a single version of SOAP.
The namespaces used in this document are shown in the following table (note that for brevity, the examples use the prefixes listed below but do not include the URIs – those listed below are assumed).
