Rotating table headers?

Hi,

 

I'm using docbook to output to pdf. I have a table 
with long column names and I would like to rotate them. I've tried the code 
below but it does'nt work. What am I doing wrong? or is'nt it supported. (I use 
Saxon XSL and Apache FOP with OxygenXML)

 

<thead>
     <row>
      <entry 
rotate="1"/>
      <entry 
rotate="1">Visa 
dokumentstrukturen</entry>
      <entry 
rotate="1">Redigera 
dokumentstrukturen</entry>
      <entry 
rotate="1">Navigera i 
dokumentstrukturen</entry>
      <entry 
rotate="1">Visa 
tidsf顤h嶚landen</entry>
      <entry 
rotate="1">Redigera 
tidsf顤h嶚landen</entry>
      <entry 
rotate="1">Redigera 
synkronisering</entry>
      <entry 
rotate="1">Visa 
dokumentstrukturen</entry>
      <entry 
rotate="1">Visa 
interaktion</entry>
      <entry 
rotate="1"> Redigera 
interaktion</entry>
      <entry 
rotate="1"> M幩gfalld av 
interaktion</entry>
     </row>
