 constructor(..., private xmlrpc:XmlrpcService, ...) {

+### XML-RPC Call
 There is only one main method to call an XML-RPC method. In order to pass parameters, you have to wrap them in an array:

 The XML response from the server is wrapped in an `Observable`, and can be parsed to a JS object with the `parseResponse` method:
-``` typescript
+``` ts
 xmlrpcCall.subscribe(data => console.log(this.xmlrpc.parseResponse(data)))
 ```

+### Custom Headers
+to set custom headers:
+``` ts
+this.xmlrpc.headers.set('Custom-Header', 'Value').
+```
+- _Note 1_: the field `headers` is of type [HttpHeaders](https://angular.io/api/common/http/HttpHeaders).
+- _Note 2_: headers 'Content-Type' and 'Accept' cannot be set and will be overridden (for obvious reasons).
