I18N Special Pages

[webxtor]

Hello.
In the doc it says 

• define directly, how the page should be displayed, instead of using a template
  
  
• customize, how the page shall be displayed as search result
  

As of search result its really easy to customize. I go to Plugins, Configure special pages, choose my type and on Edit Special Page Type page there is a tab Search there is a textarea field for my custom php, plus there is an example of the default code so its all very easy here.

But when it comes to page view edit, I am stuck. I believe there is View tab for this on thesame settings page. There I have 2 fields: header and content. But no examples here!
When I put something to header it adds it to header, adds, but not replaces. Ok, I dont need header, I just want to edit page content.
So when I put anything to the content field, nothing happens! Yes, I see there are languages, I put in all of them. I even tried to put whole default template code there and finally gotten some result, but strange to the bone: all it did is took page title and put it under meta description and the rest was untouched.
Totally wierd.
Would be very glad to get any hints on how can I customize special page view without creating custom template.
Thanks
