I'm not aware of anything that would prevent the Infoset from being
described in Grove notation.  There aren't many people alive who
actually know Groves (we couldn't all fit in a Cessna, but we probably
could squeeze into a Dash-8 with a few empty seats), so it had no real
familiarity advantage.

By the way, for a database-like XML thingy, see

The DATAX interfaces can be used on top of an RDBM as easily as they
can on top of the default in-memory data structures.

All the best,
