What's changed in WS-I Basic Profile 1.1?

  • Article

Sherman Mohler of Cisco's Learning Institute completed a comparison of WS-I Basic Profile 1.1 with WS-I Basic Profile 1.0. I've included a copy of the document below for your enjoyment.

New Requirements as of WS-I 1.1

R9980 - An ENVELOPE MUST conform to the structure specified in SOAP 1.1 Section 4, "SOAP Envelope" (subject to amendment by the Profile).

R1033 – An ENVELOPE SHOULD NOT contain the namespace declaration xmlns:xml="https://www.w3.org/XML/1998/namespace". C

R1034 – A DESCRIPTION SHOULD NOT contain the namespace declaration xmlns:xml="https://www.w3.org/XML/1998/namespace". C

R1032 – The soap:Envelope, soap:Header, and soap:Body elements in an ENVELOPE MUST NOT have attributes in the namespace "https://schemas.xmlsoap.org/soap/envelope/".

R1127 – A RECEIVER MUST NOT rely on the value of the SOAPAction HTTP header to correctly process the message.(SOAP12)

R2803 – In a DESCRIPTION, the namespace attribute of the wsdl:import MUST NOT be a relative URI.

R4005 – A DESCRIPTION SHOULD NOT contain the namespace declaration xmlns:xml="https://www.w3.org/XML/1998/namespace".

R2030 – In a DESCRIPTION the wsdl:documentation element MAY be present as the first child element of wsdl:import, wsdl:part and wsdl:definitions in addition to the elements cited in the WSDL1.1 specification.(WSDL20)

R2212 – An ENVELOPE MUST contain exactly one part accessor element for each of the wsdl:part elements bound to the envelope's corresponding soapbind:body element.

R2213 – In a doc-literal description where the value of the parts attribute of soapbind:body is an empty string, the corresponding ENVELOPE MUST have no element content in the soap:Body element.

R2214 – In a rpc-literal description where the value of the parts attribute of soapbind:body is an empty string, the corresponding ENVELOPE MUST have no part accessor elements.

R2755 – The part accessor elements in a MESSAGE described with an rpc-literal binding MUST have a local name of the same value as the name attribute of the corresponding wsdl:part element.

Old Requirements removed from WS-I 1.1

R0004 – A MESSAGE MAY contain conformance claims, as specified in the conformance claim schema.

R0005 – A MESSAGE's conformance claims MUST be carried as SOAP header blocks.

R0006 – A MESSAGE MAY contain conformance claims for more than one profile.

R0007 – A SENDER MUST NOT use the soap:mustUnderstand attribute when sending a SOAP header block containing a conformance claim.

R3020 – REGDATA of type uddi:tModel claiming conformance with a Profile MUST be categorized using the ws-i-org:conformsTo:2002_12 taxonomy.

R3030 – REGDATA of type uddi:tModel claiming conformance with a Profile MUST use the ws-i-org:conformsTo:2002_12 categorization value corresponding to the conformance claim URI for that Profile.

R3021 – A REGISTRY MUST support the WS-I Conformance category system by adding the ws-i-org:conformsTo:2002_12 tModel definition to its registry content.

R3005 – REGDATA other than uddi:tModel elements representing conformant Web service types MUST NOT be categorized using the ws-i-org:conformsTo:2002_12 taxonomy and a categorization of "https://ws-i.org/profiles/basic/1.0".

R3004 – REGDATA of type uddi:tModel MUST be constructed so that the conformance claim it makes is consistent with the conformance claim made by the wsdl:binding to which it refers.

R4001 – A RECEIVER MUST accept messages that include the Unicode Byte Order Mark (BOM).C

R1010 – A RECEIVER MUST accept messages that contain an XML Declaration.

R1012 – A MESSAGE MUST be serialized as either UTF-8 or UTF-16.

R1018 – The media type of a MESSAGE's envelope MUST indicate the correct character encoding, using the charset parameter.

R1110 – An INSTANCE MAY accept connections on TCP port 80 (HTTP).

R2020 – The wsdl:documentation element MAY occur as a child of the wsdl:import element in a DESCRIPTION. WSDL20

R2021 – The wsdl:documentation element MAY occur as a child of the wsdl:part element in a DESCRIPTION. WSDL20

R2024 – The wsdl:documentation element MAY occur as a first child of the wsdl:definitions element in a DESCRIPTION. WSDL20

R2728 - A wsdl:binding in a DESCRIPTION that omits the use attribute on a contained soapbind:fault element MUST be interpreted as though use="literal" had been specified. C

Referenced Specifications

Identical except WS-I 1.1 also references: “Namespaces in XML 1.0”

Extensibility Points

Identical except WS-I 1.1. includes:

E0006 - Envelope serialization - The Profile does not constrain some aspects of how the envelope is serialized into the message

E0024 - Namespace Attributes - Namespace attributes on soap:Envelope and soap:Header elements

E0025 - Attributes on soap:Body elements - Neither namespaced nor local attributes are constrained by SOAP 1.1

E0019 - TLS Cyphersuite - TLS allows for the use of arbitrary encryption algorithms

E0020 - TLS Extensions - TLS allows for extensions during the handshake phase
