22. Platform - UI Generation Model

Creation of the UI begins with the transformation of the XML schema into an XForms instance document.

XForms is a W3C Candidate Recommendation (Nov 2002) for the next generation of Web Forms that separates the content of the form from its presentation

The schema can be used to validate the instance collected by the form

Not every element and attribute in the schema needs to be in the form, posing a configuration challenge
