docbook article with cover

Hi there!

I'm learning to use DocBook and I was trying to figure 
out how to make an article with coverpage... Or alternatively a book 
without the need of chapters (although i think I'd prefer the first 
thing) The xsl stylesheet scheme seems so flexible that I thought it 
must be possible... but i was lost in tons of sites on xsl stylesheet 
discussions...

I will continue my search, but I thought maybe i could 
just ask you (since you are the one person that surely knows that 
already) if it was possible and maybe if you had the appropriate 
reference for me :)

many, many thanks in advance,

Cristóbal Vio

Update: 

I've continued my search and it still isn't clear to me if I need to do a
 new xsl style or alter the dtd part concerning the article type.

Still hoping you can answer.

Thanks in advance,

Cristóbal
