Both SUR and HLM can be seen as special cases of a SEM (see:
<http://blog.stata.com/2011/09/28/multilevel-random-effects-in-xtmixed-and-sem-the-long-and-wide-of-it/>),
so you can probably, with quite a bit of creative data preparation and
modeling, estimate such a model using -sem-.

Hope this helps,
Maarten
