Less than one hour ago, I sent this press release and testimonial  
sheet to you regarding the WSDL announcement. It contained an as-yet  
approved testimonial from IBM. This email contains the approved  
version. I apologize for the confusion.

Kind regards,


Today, W3C completed work on a critical Web Services Standard, adding  
features that permit it to work in both HTTP applications and WS-*  
environments as well. Web Services Description Language (WSDL) 2.0 is  
the first standardized version of the WSDL technology. For more  
information, please contact Janet Daly, W3C Global Communications  
Officer, at +1 617 253 5884 <janet@w3.org> or the W3C Communications  
Team representative in your region.

http://www.w3.org/ -- 27 June 2007 -- Today, W3C has finalized a Web  
services description language with full support of the primary  
protocol for the Web, HTTP, and the most frequently implemented Web  
services protocol, SOAP. Web Services Description Language (WSDL) 2.0  
incorporates both the improvements for WSDL 1.1 found in the WS-I  
Basic Profile, and builds in inheritance, import functions, improved  
description of faults and errors, and full HTTP and SOAP support.  
Rigorous testing and interop sessions, including week-long  
programming marathons by the Web Services Description Working Group  
itself, have produced a solid interoperable standard that delivers on  
the goals of the initial WSDL 1.1 version, and also meets the needs  
of Web applications developers today.

"It's been a long time in development, but developers can see it's  
been worth the wait," explained Jonathan Marsh, co-chair of the W3C  
Web Services Description Working Group and Director of Mashup  
Technologies at WSO2. "In addition to the rigorous interoperability  
testing, we're pleased to have given developers the HTTP binding,  
which provides simple Web-friendly access to a service when the  
advanced features available in the SOAP stack, such as WS-Addressing,  
WS-Security, and WS-ReliableMessaging, aren't required."

WSDL 2.0 Development Began with Stringent Interoperability  
Requirements, Finished with Conversion Tools and Support in Emerging  
Web Standards

Wide interest in SOAP 1.1 and WSDL 1.1 marked the beginning of Web  
Services pursuits. The hope of interoperability in the initial, non- 
standardized versions was not immediately fulfilled in spite of the  
large number of developers who moved to that model for applications  
development. WS-I, for example, formed to create profiles based on  
non-standard versions of the popular Web Services technologies.

Against this backdrop, the W3C Membership urged the Consortium to  
develop an interoperable WSDL standard. Through significant issue  
tracking by the Working Group itself, and through cooperative work  
with the WS-I Basic Profile Working Group, it was possible to  
identify initial improvements and build from there for both SOAP 1.2  
and WSDL 2.0.

Those who have built implementations that conform to the WS-I Basic  
Profile may use a converter to WSDL 2.0, thus easing the transition  
to the new standard and enabling use of new features.

Further, WSDL 2.0 support is built into critical emerging Web  
services standards, including Semantic Annotations for WSDL (SAWSDL)  
and WS-Policy 1.5, both anticipated in September 2007.

WSDL 2.0 Lets Developers Choose WS Application Development Models;  

With the increased popularity of REST-model as well as SOAP over  
HTTP, the Working Group recognized the clear need for complete HTTP  
support in Web application descriptions. As a result, WSDL 2.0 has  
complete HTTP and SOAP support, making it useful for both simple Web  
applications and Web Services applications that require additional  

WSDL 2.0 Created and Implemented by Industry Leaders; Wide Deployment  

The Web Services Description Working Group has enjoyed the  
participation of many industry leaders in the area of applications  
development and is co-chaired by Marsh and Tony Rogers of CA. Current  
participants in the WSD Working Group are, in alphabetical order,  
Adobe Systems Inc.; Agfa-Gevaert N. V.; BEA Systems, Inc.; BT; CA;  
Canon, Inc.; IBM; University of Innsbruck; IONA Technologies, Inc.;  
Maryland Information and Network Dynamics Lab at the University of  
Maryland; Microsoft Corporation; Oracle Corporation; Rogue Wave  
Software; SAP AG; Sonic Software; Sun Microsystems, Inc.; TIBCO  
Software, Inc.; WSO2; and Xerox Corporation.

Many companies have stated that they expect to support WSDL 2.0 in  
upcoming product releases, including Adobe Systems Inc.; CA; IBM; Sun  
Microsystems, Inc; webMethods; and WSO2. Details on support and  
implementation plans are provided in the testimonial sheet.

Testimonials for WSDL 2.0 from IBM, WSO2, and WS-I

IBM congratulates the W3C Web Services Description Working Group on  
achieving Recommendation status for WSDL 2.0.  New features in WSDL  
2.0 will enable customers to achieve better integration and synergy  
between simple HTTP-based services (REST) and SOAP-based Web  
services.  Customers will be able to leverage their existing  
investments in implementations that use the WS-I Basic Profile (which  
documents correct use of WSDL 1.1) in parallel with the new WSDL 2.0  

Our product support for WSDL 2.0 begins with the IBM CICS Transaction  
Server for z/OS V3.2, generally available on 29th June 2007.  The  
CICS Web Services Assistant has been enhanced to support both WSDL  
1.1 and 2.0, and to transition between the two, to ensure that CICS  
will interoperate with modern tools, infrastructure and service  
components in the SOA environment.
  -- Karla Norsworthy, Vice President, Software Standards, IBM

     WSO2 is very pleased to see the WSDL 2.0 family of  
specifications become W3C Recommendations. These specs represent the  
distillation of years of accumulated industry experience with WSDL  
1.1-based interoperability. As acontributor to the open source Apache  
Axis2 project, WSO2 has helped build comprehensive WSDL 2.0 support  
into the latest versions of Axis2. Axis2 and its new WSDL 2.0 support  
is incorporated into the WSO2 Web Services Application Server, a free  
and open source platform for creating, consuming, and managing Web  
     -- Sanjiva Weerawarana, CEO, WSO2

     WS-I congratulates the W3C Web Services Description Working  
Group on WSDL 2.0 becoming a Recommendation. Many WS-I members have  
worked closely with the W3C Working Group, providing feedback on how  
to improve on the original WSDL 1.1 submission. WSDL 1.1 is part of  
the WS-I Basic Profile 1.1, based on WSDL 1.1, SOAP 1.1 and UDDI 2.0,  
which provides interoperability guidance to developers who are  
generating Web services to be deployed into a heterogeneous environment.
