Deleting schemas or schema versions
You can delete a single version of a schema or all versions
of a schema. Deleted schemas and schema versions cannot be restored.
Before you begin
Before you attempt to delete a schema or schema version, verify that both of these conditions are true:
- The schema is not currently associated with a user database. If it is, you must first delete the user database.
 - The schema is not currently checked out. If it is, you must check it in.

To delete a schema or schema version from the schema repository:
- Start the Designer.
 - In the Schema Repository Explorer view, select the schema or schema versions that you want to delete.
 - Right-click the selected items and click Remove.
 - Click OK to delete the items.
