My setting:

Compiler: DMD 1.056
Library: Tango 0.99.9
OS: Windows 7

What I have done so far:

I have managed to build via API a GPX file and know how to format it and display it on the console.

My code:

module SwathGen;

import 
  tango.io.Stdout,
  tango.text.xml.Document,
  tango.text.xml.DocPrinter;

void main(char[][] args)
{   
    auto gpxdoc = new Document!(char);

    gpxdoc.header;

    gpxdoc.tree 
        .element(null,"gpx")
