[XeTeX] PDF properties like title, author and keywords

[Thomas Bohn]

I really like XeTeX but why can't I modify the properties of the PDF  
with hyperref? When I use a line like this:

\usepackage[pdftitle={Anschreiben an XYZ},pdfauthor={Thomas Bohn}] 
{hyperref}

Only all properties are gone which is not all that bad, since XeTeX  
annoys with the weird PDF title "XeTeX output [Date]" You will find  
this title a lot via Google.

I hope someone can help me, Google couldn't.
