sep seems not to work for tree format

From semantic-mediawiki.org

So far I have not used this result format though I am looking forward to. Hmm, just by looking at the documentation it should work to get a separator in there somehow. Did you just try |sep=, to see what happens?

Hi kgh,

sorry for the late reply. Of course I tried, as mentioned above.

Kind regards
