[news.eclipse.platform] Umlaut in exsd files

[Simon Eggler <simon.eggler@xxxxxxxxxx>]

umlaute in schema defintion files are displayed as weired characters in 
the webbrowser view of the documentation preview. i tried replacing the 
umlate with the following substitute entities:
Ä      Ä
Ö      Ö
Ü      Ü
ä      &#228
ö      ö
ü      ü
ß      ß

that does not work, though.

how must i encode umlaute in my exsd description in order to get a 
correct result?

thank you
simon
