Custom objects and editioning in R12.2

Hi,

1) during the EBS upgrade to R12.2 will my custom views be automatically turned on for editioning and will # be added to the end of the view name, e.g. from view XXMEL.XXMEL_ATP_ORDERS to editioned view XXMEL.XXMEL_ATP_ORDERS#?

2) can I create a custom view in a custom schema, e.g. XXMEL.XXMEL_ATP_ORDERS, and not use the # at the end of the name?

3) where should I put my custom sequences, i.e. in my custom schema XXMEL or APPS?

Thank you,

Mauro.
