  // Note: The application does not need to explicitly set the following
  // headers: x-ms-date, Authorization.  These headers
  // are automatically set by Chilkat.

  // In this example, we are getting the ACL permissions of the container named "mycontainer".

  // Load the XML response for parsing.
  // An example of the response XML is shown below.
  const xml = new Xml();

  // Use the ChilkatPath method to get various pieces of information out
  // of the XML.  For example:

  console.log(`Id = ${xml.chilkatPath('SignedIdentifier|Id|*')}`);
  const startTimeStr = xml.chilkatPath('SignedIdentifier|AccessPolicy|Start|*');
  console.log(`Start Time = ${startTimeStr}`);

  // The date/time string can be loaded into a CkDateTime object for 
  // access to individual parts, or conversion to other formats.

  // For example..
  const bLocalTime = true;
