Note:

Do not customize the same SOA composite application for different layer values. Layer values are the customizations made to the base composite, as described in Introduction to Customizing SOA Composite Applications. Only a single layer value for customization is supported. If you must support another layer value, always import the base composite into a different project and change the composite name to be specific to the layer value you want to customize. This approach is also useful for deployments in which you do not want to deploy different layer values with the same composite name.
