+This section describes the unified manifest for readers who are familiar with the current XML manifest. Some points to keep in mind:
 
 - The unified manifest is JSON-formatted.
 - JSON doesn't distinguish between attribute and element value like XML does. Typically, the JSON that maps to an XML element makes both the element value and each of the attributes a child property. The following example shows some XML markup and its JSON equivalent.

+The root level of the unified manifest, which roughly corresponds to the **\<OfficeApp\>** element in the current XML manifest, is an anonymous object.
 
-The children of **\<OfficeApp\>** are commonly divided into two notional categories. The **\<VersionOverrides\>** element is one category. The other consists of all the other children of **\<OfficeApp\>**, which are collectively referred to as the base manifest. So too, the unified manifest has a similar division. There is a top-level "extensions" property that roughly corresponds in its purposes and child properties to the **\<VersionOverrides\>** element. The unified manifest also has over 10 other top-level properties that collectively serve the same purposes as the base manifest of the XML manifest. These other properties can be thought of collectively as the base manifest of the unified manifest.
