void beginAttach( AcDbDatabase*, const ACHAR*, AcDbDatabase* ) override;
Description
This callback function indicates that the external reference database pointed to by pFrom is to be attached to the database pTo.

If the pFrom database is already present as an xref in the pTo database, then this notification is not sent for any subsequent XREF attach operations.
