8284: concrete proposal

All of our specs contain a reference to WSDL 1.1. Those references 
should be changed from:

*WSDL 1.1*

    W3C Note, "Web Services Description Language (WSDL) 1.1"
    <http://www.w3.org/TR/2001/NOTE-wsdl-20010315> , E. Christensen, et
    al., Editors. World Wide Web Consortium (W3C), 15 March 2001
    Available at http://www.w3.org/TR/2001/NOTE-wsdl-20010315.

to

*WSDL 1.1*

    Section 4, "Service Description", ISO/IEC 29361
    <http://www.iso.org/iso/catalogue_detail.htm?csnumber=45422>,
    International Organization for Standardization (ISO), 15 June 2008.
    Available at http://www.iso.org/iso/catalogue_detail.htm?csnumber=45422

All of our specs also have a "WSDL" appendix. The following paragraph 
should be added to this these sections, after the link to the normative 
WSDL, but before the  "A non-normative copy . . ." paragraph.

This description conforms to the constraints and clarifications to the 
W3C Note, "Web Services Description Language (WSDL) 1.1" 
<http://www.w3.org/TR/2001/NOTE-wsdl-20010315> described in Section 4, 
"Service Description", of ISO/IEC 29361 
<http://www.iso.org/iso/catalogue_detail.htm?csnumber=45422>. 
Implementations that publish derivations of this description (e.g. for 
the purposes of expressing a particular binding or attaching policy) 
must similarly conform to these constraints and clarifications.
