Hi Zhongbao.

I'm actually not responsible for this one(!) - the members were taken out
of the "default" bdst at some point for reasons that I don't know. But if
there is an interest in this kind of "basic" TPC data in the DSTs I can
make sure they are there in the next generation.

If noone else comments I'll just put it back in, but maybe someone has
other opinions?
