Further information
1. This procedure is intended to assist users to write code interacting with DMP resources that will work both within Xpress DMP components and when executed locally.
2. If you pass an authtoken value, all HTTP requests made through this resource will be decorated with an appropriate Authorization: header.
3. If you pass an authheaders value, all HTTP requests made through this resource will be decorated with HTTP headers read from this array (indices are the header names).
4. You should check the status attribute of the dmpresource after calling this procedure.
