By the time that the outer tag was able to act on the reference to the inner tag
instance, that inner tag would have been released (and possibly recycled). Thus,
any reference to the inner tag would be useless.
A different approach to this problem could be something like this: in the inner
tag, you can follow the chain of parent tags until you find the outer tag that you
want. Then, call some property setter methods on the outer tag instance to save
whatever information you want to keep.
