It might be enough to invent a struct-level attribute allowing

manual assignment of the tag value should be workable.
Yes, I'm aware of this issue, and that was also more or less my idea.
(Well, before the introduction of per-struct attributes, I was thinking
about parsing nodes.h to see if the tag is listed explicitly. But this
is probably better.)
