titelpage, title spec file, subtitle

Hey everybody!

I tried to get the titlepage customazing for both the html and fo 
output, but i 
don't.(http://www.sagehill.net/docbookxsl/HTMLTitlePage.html#TitlePageElems)

Can I overwrite the default titlepage? Or should I create an external 
titlepage.xml and include this titlepage.xml into my entire document?

On top of that I need to customize the subtitle in my document!

My aim: To get a simple titlepage with title, subtitle and a logo below 
them.A titlepage without footer and pagenumber!

Best regards, Lwam
