removing an object from obj$

My supervisor tasked me to figure out how to remove an invalid object in the database. it's an XML (XDB owned) object and I've used dbms_xmlschema.deleteSchema() to remove the object, but a reference still exists in obj$ and it has a status of 5 (invalid).

Oracle support said to do this .....

delete from obj$ where name=....;

My question is this. Has anyone tried this before? Support said that it's risky and there is the possibility of db corruption.

I'm running 9.2.0.8 on AIX.

TIA! Jeremy
