On behalf of the Semantic Annotations of WSDL Working Group I wish to
comment that

http://www.w3.org/TR/2006/WD-wsdl20-rdf-20060518/#genericext
[[
Extension elements are represented as XML literals containing the
whole extension XML elements (and should also include all the in-scope
namespaces and the XML base);
]]

elides a bunch of points that are handled by canonicalization. I
recommend the following text (not specifically endorsed by SAWSDLWG):

[[
Unknown optional extensions can be represented in the RDF
representation using the properties extensionElement and
extensionAttribute. Each extension element is represented as an XML
literal (see [RDF] section 5.1, XML Content within an RDF Graph)
containing a canonicalised representation [C14N] of the entire
extension XML element.
]]

where [RDF] references the Concepts and Abstract Syntax, alreay in
section 5, and [C14N] references
[[
[C14N]
    Canonical XML. W3C Recommendation. J. Boyer. March 2001. 
    Available at http://www.w3.org/TR/xml-c14n and
    http://www.ietf.org/rfc/rfc3076.txt 
]]
