r_univar accepts is "map":

Now I do not have its xml and zcfg files to check, but if I don't
remember wrong there should have been a parameter like
"grass_band_number"...

Actually we have a similar problem also with r.horizon. We created the
GRASS XML file, generated the zcfg and python files from it and added
the service to ZOO (after changing some square brackets to normal ones
in the Titles, otherwise ZOO got messed up).
The problem is that the DescribeProcess shows only two inputs
(http://131.175.143.108/cgi-bin/zoo_loader.cgi?Service=WPS&Request=DescribeProcess&Version=1.0.0&Identifier=r_horizon),
despite having a lot more in the zcfg file
(http://pastebin.com/TTNfRQ99). It seems that ZOO keeps only the
"ComplexData" ones and discards the "LiteralData" ones.

I really do not have any idea about what could be the problem.
