curl -X PUT -T aa.pdf http://localhost:9998/tika

However I want to use the http module[1] I have tried:

let $file:="C:\tmp\aa.pdf"
let $request :=
  <http:request  method='PUT'    >

    <http:body media-type="application/octet-stream">{
      fetch:binary($file)
    }</http:body>
    </http:request>
let $r:= http:send-request($request,$tika)

I have tried this with various values for http:body/@method with no sucess.
The content-length header from this does not match the one sent by curl. 
This did not work either (no body?):

let $file:="C:\tmp\aa.pdf"

let $request :=
  <http:request  method='PUT'    >
    <http:body media-type="text/plain" src="{$file}"/>
  </http:request>
let $r:= http:send-request($request,$tika)
