ampersand (&) in Pathurl of DOCTYPE xmeml when sent to AME fails

The FCP xml sent to AME has an ampersand in the filepath used in the <pathurl> tag as shown below

//localhost/DEMOSERVER/MediaStore/HighRes/test&test/test.mxf

And AME couldnt accept ampersand even its escaped as &  or %26

Please could you advise.
