DOCBOOK-APPS: title page on two pages

I'm trying to have the data from articleinfo spread over two recto 
pages. But so far, I had no success in it.

If I try to define a new titlepage element whose is article2, I get 
nothing because the informations are taken from article2info. I cannot 
say that I want twice a titlepage-content with side="recto". I cannot 
insert a page break, because I will lose the verso side of the very 
first page.

Can someone help me ?

Thanks.
