turn off hyphenate

hi,
I want to convert docbook over fo to pdf.
For fop 0.20.5 I want to turn of hyphenation.
The result could be: <fo:block hyphenate="false">
but I'm not sure if this is the right way to change this.
I use docbook-xsl-1.65.1\fo to generate fo.
And the I edit every fo:block in the fo file ...
There must be an other way ...

tia Thomas
