They are allowed to use this designation, but in practice it seems to be
rarely done.  The only case I've ever seen of the DE being used is dark
chocolate Toblerone.  OU (U in a circle) doesn't use the DE
designation at all, but I believe OK (K in a circle) does.

According to the OU's website at http://www.ou.org/kosher/policy.htm:

    OUD Products are DAIRY. These products either contain dairy
    ingredients, or have been processed on dairy equipment.

This is the one we use as well.  I believe they have pareve formulations
in both stick and tub form.
