1 Scope

This Recommendation | International Standard specifies the messages and encodings that enable the use of Fast Web Services, together with the means of description of such services.

The protocol used to support these services satisfies the requirements of the SOAP processing model (see W3C SOAP Part 1, clause 2) and is based on the transfer of:
a) ASN.1 SOAP messages that contain embedded ASN.1 encoded values and embedded fast infoset documents; and
b) fast infoset SOAP messages.

This Recommendation | International Standard also specifies:
-an ASN.1 module for ASN.1 SOAP that defines the Envelope type (a value of this type corresponds to an ASN.1 SOAP message);
-a conceptual mapping between ASN.1 SOAP messages and W3C SOAP messages (defined as an instance of the XML Infoset, see W3C SOAP Part 1, clause 5);
-an extension to the W3C SOAP processing model for the processing of embedded ASN.1 encoded values;
-the ASN.1 SOAP HTTP Binding, which is a modification and extension of the W3C SOAP HTTP Binding (see W3C SOAP Part 2, clause 7), for the transfer of ASN.1 SOAP messages;
-support for the transfer of W3C SOAP message infosets serialized as fast infoset documents (fast infoset SOAP messages) using the W3C SOAP HTTP Binding (see W3C SOAP Part 2, clause 7);
-SOAP-oriented service descriptions that define the interface to and the semantics of Fast Web Services.

Two Multipurpose Internet Mail Extensions (MIME) media type names are allocated to identify:
-ASN.1 SOAP messages encoded using Basic Aligned PER;
-fast infoset SOAP messages.
