Remarks
Extensibility points are a mechanism by which an app can add functionality in a manner defined by the operating system. An example of an app extensibility point is the ability to create a file type association and enable your app to be the default handler for files with a specific file name extension.
The Extension elements that can be included under the Application/Extensions element are enforced by the XML schema. Each of these Extension elements have a required Category attribute that specifies one or more extension points that the extension supports. Some extensions support both application and package extension categories. The following table lists the extension categories supported for application extensions and the associated Extension element that supports each category. A category can be supported for multiple extensions as a versioning mechanism.
