For issue 1737 we agreed last face-to-face to remove macroSpec/@type
on 2018-10-01 (the same date we are removing all the data.* macros, I
guess). I have just put the @validUntil on to make that happen.
But the timing concerns me a little -- when is our next release going
to be? Unless it is this month, people will have < 5 months to see
the red health warning.
BTW, we've agreed to deprecate data.* on 2018-10-01, but who is doing
that and is there an issue open for it? (I have this nagging feeling
all of a sudden that it's me. :-)
