A rule like:

*[data_type < 4] [data_type > 5] *
*
*
only matches when the data_type property is *both* less than 4 and greater
than 5.  The CSS translator optimizes that out since it can't ever happen;
that's why you end up with an empty SLD.  If you want to match when either
of these conditions is met, just separate them with a comma.
