Yes and no. Actually there is not really. But some is simulated for
readability of tags with the `aad:' `zc:'" part of the tag names. It
has effects only on the _display_ of the tags (in the client).

There is some in the alphabetic part at the beginning of the name of
the tag, but it is work in progress only (to be dealt with by
classifiers).

They can create the (display) hierachy in the same time. This feature
may also not be used, but we have had feedback (in the demo server)
that there were too many tags to be read at once.

Alternative ways to solve this problem might be considered.
