2.2.1.1 Preferences Policy File Format

The contents of a Preferences Policy file MUST be an XML document.

An XML schema is defined for each Preferences Policy file. All schemas share a common structure: a single top-level outer element that MUST be an XML sequence of zero or more inner elements. Each inner element MUST define a properties attribute. Abstractly, an inner element represents a single instance of an element, such as an environment variable or a data source. The outer element is a container of inner elements. The abstract XML schema is in section 2.2.1.1.1.
