Subject: Re: AW: [ubl] Re: Next Version & Customization

i support Michael's view on this.  We should be aiming to demonstrate 
how customization works.

i also agree that we cannot just customize the schemas - we have to have 
customized models as well.  how else can we maintain the link between them?
