I don't understand your response. I did not cite any specific text or
example of the specification; I am asking why using

  POST /sparql/ HTTP/1.1
  Host: www.example
  User-agent: my-sparql-client/0.1
  Content-type: application/xml


is good, and using

  POST /sparql/ HTTP/1.1
  Host: www.example
  User-agent: my-sparql-client/0.1
  Content-type: application/sparql-query


is not so good. I said that this seems to be a bad thing because the
interface does not allow it and because "The queryHttpGet binding should
be used except in cases where the URL-encoded query exceeds practical
limits, in which case the queryHttpPost binding should be used." To be
yet more precise, why

   <operation ref="tns:query" wsdlx:safe="true" whttp:method="POST" 
                                application/xml" ...

and not

   <operation ref="tns:query" wsdlx:safe="true" whttp:method="POST" 
                                application/xml" ...
