thanks for your answer Hans.
Now i found some examples. Bot for me it doesnt work. I tried the documents in 
http://minimals.contextgarden.net/current/context/test/doc/context/tests/mkiv/tags/
but there are  no spaces between words in reflow-mode.
I am using adobe reader 9 for Linux and 
ConTeXt  version: 2011.10.14

LG stefan
