Okay, I just having come from the school asked this same topic/question to the Standards squadron SSM. I could not get a straight answer. However everyone in any chain of command that I asked emphatically said that the PLQ was not considered in the wearing of a TRADE badge as the PLQ/CLC/etc.. was not a TRADE SPECIFIC course. I tend to agree with that point and those of us at the school put up our "tank w/crown" as a DP3 qualified soldier. When I worked in training squadron a while back we had two version of the trade badge sheet. Both versions discussed in this thread were represented but like I said, as of August of this year, there is no concrete answer to the 011/00005 trade badge question.
