A method and system are described for providing Digital Rights Management-protected (DRM-protected) electronic content to user equipment whose operation is at least in part supported by a platform. When the content is received at a rendering server within the platform, the rendering server requests validation of usage rights associated with the content from a platform DRM module. The DRM module determines whether a DRM content type of the content is associated with a support module in an application domain and, if so, supplies the validation request to the associated support module via an interface with the support module. Otherwise, the validation request is processed at the DRM module. In either case, the content is rendered at the rendering server and made available to the user equipment according to a response to the validation request. The DRM functionality of the support module can be changed by third parties.
