Erik,
You could use the documentation element, specified in the WSDL 1.2
specification, for this purpose (cf.
http://www.w3.org/TR/wsdl12/#eii-documentation). This element is also
present in WSDL 1.1. You can include whatever you want in here, so long as
it's valid XML.
Note that you cannot guarantee the presence of this element with the WSDL
parser (you probably wouldn't want to either), so you should verify it's
presence programmatically, and generate an application-level exception as
appropriate, if this information is required.
