      summary: Add a new transform
      description: Adds a new transform to the server. If the content type used is application/xml the server will assume a <transform> definition is being posted, and the XSLT will have to be uploaded separately using a PUT request with content type application/xslt+xml against the transformation resource. If the content type used is application/xslt+xml the server will assume the XSLT itself is being posted, and the name, sourceFormat, outputFormat, outputMimeType query parameters will be used to fill in the transform configuration instead.
