How to identify objects created by registering xml schema

Question

Hi Everyone,
We are using Oracle 9i Rel2. I have registered an XML schema and I saw that there were several objects created for it table ,some types and a trigger . For some build purposes I want to exclude all of these objects which are associated with xml schema and should be able to drop and recreate the whole of oracle schema.
I see the user_types table does not have any parameter to indicate that these are autogenerated or are different. In user_types they look like any other type that a user would have created. Do any of you know how to differentiate these types created by registering XML schemas from the normal types.
Thanks for your help

Answer 1

There is no way I know of to differentiate between a type created by Schema Registration and another Type. You can query the XML Schema itslef to get the Typenames it relies on.
