I have yet to see a permanent blood donation centre at a school, but I
would just place a node with the healthcare tags in the school area and
call it a day.
Adding everything on the school boundary seems very odd to me, I have never
seen that done. For renderers, I think it must be a nightmare. I know we're
not supposed to tag for the renderer but any data consumer would have
trouble interpreting dual-tagged objects.

So to me, healthcare=blood_donation is pretty stand-alone (just like
shop=*) and not an attribute of a school, a shop or even a hospital for
that matter. I'd use it on a node without any other tags, but on a way of
course with building=yes or whatever tags are relevant. (Also see the
examples on the proposal page – do you agree with them or would you tag
them differently?)

I could add a piece about making sure to use a building tag to the page,
but IMO then we'd have to do that on the wiki pages for all shops, most
amenities, etc...
Actually that might not be a bad idea? We could write a template and
include it on those pages. I've seen people using JOSM not including
building tags quite a few times.
