Policy Feature Overview
A policy feature is an assembly or other piece of code that provides some content management functionality to Microsoft Office SharePoint Server 2007, and possibly to 2007 Microsoft Office system client application documents as well.
If you want to create a policy feature that provides functionality within 2007 Microsoft Office system client applications, you must create the custom code that enforces the policy within the applications and also deploy that code onto the computers running the applications. The policy XML is demoted and stored in client documents, such as 2007 Microsoft Office system documents, as read-only instructions for how to execute the policy. Office SharePoint Server 2007 does not handle the deployment of the code that enforces the policy within the 2007 Office system client application.
Policy Feature Requirements
Office SharePoint Server 2007 requires each policy feature to do the following:
Implement the IPolicyFeature interface.
For more information about the IPolicyFeature interface, see IPolicyFeature Interface Overview.
This is usually done as part of deploying the policy feature as a Windows SharePoint Services Feature. For more information, see Working with Features in the Microsoft Windows SharePoint Services 3.0 SDK.
