My guess was 0x01. But it turns out that I was wrong :) Actually
it is not a valid style because you can't have tag_a!=yes all by itself.
If it were tag_a=yes then the answer would still be 0x01
because that is the first rule with a definition that matches.
It seems that the action rules are being used a lot more than I thought
going some way beyond what they were designed for. We need to look at what
the actions are being used for. I get the impression that a lot of it is
to normalize inconsistent tagging, so perhaps we need a separate stage
where that is done explicitly.
