    <summary>Provides access to App Functions.</summary>
    <remarks>
      <para>Provides access to App Functions. App Functions is currently a
            beta/experimental preview feature.</para>
      <para>An app function is a piece of functionality that apps expose to the system for cross-app
            orchestration.
            
            &lt;h3&gt;Building App Functions&lt;/h3&gt;</para>
      <para>Most developers should build app functions through the AppFunctions SDK. This SDK library
            offers a more convenient and type-safe way to build app functions. The SDK provides predefined
            function schemas for common use cases and associated data classes for function parameters and
            return values. Apps only have to implement the provided interfaces. Internally, the SDK converts
            these data classes into <c>ExecuteAppFunctionRequest#getParameters()</c> and <c>ExecuteAppFunctionResponse#getResultDocument()</c>.
            
            &lt;h3&gt;Discovering App Functions&lt;/h3&gt;</para>
      <para>When there is a package change or the device starts up, the metadata of available functions is
            indexed on-device by <c>AppSearchManager</c>. AppSearch stores the indexed information as an
            <c>AppFunctionStaticMetadata</c> document. This document contains the <c>functionIdentifier</c>
            and the schema information that the app function implements. This allows other apps and the app
            itself to discover these functions using the AppSearch search APIs. Visibility to this metadata
            document is based on the packages that have visibility to the app providing the app functions.
            AppFunction SDK provides a convenient way to achieve this and is the preferred method.
            
            &lt;h3&gt;Executing App Functions&lt;/h3&gt;</para>
      <para>To execute an app function, the caller app can retrieve the <c>functionIdentifier</c> from
            the <c>AppFunctionStaticMetadata</c> document and use it to build an <c>ExecuteAppFunctionRequest</c>. Then, invoke <c>#executeAppFunction</c> with the request to execute
            the app function. Callers need the <c>android.permission.EXECUTE_APP_FUNCTIONS</c> permission to
            execute app functions from other apps. An app can always execute its own app functions and
            doesn't need these permissions. AppFunction SDK provides a convenient way to achieve this and
            is the preferred method.
            
            &lt;h3&gt;Example&lt;/h3&gt;</para>
      <para>An assistant app is trying to fulfill the user request "Save XYZ into my note". The assistant
            app should first list all available app functions as <c>AppFunctionStaticMetadata</c> documents
            from AppSearch. Then, it should identify an app function that implements the <c>CreateNote</c>
            schema. Finally, the assistant app can invoke <c>#executeAppFunction</c> with the <c>functionIdentifier</c> of the chosen function.</para>
