Init for WAP 2.0 and XHTML Mobile Profile support. WAP20Plugin is a

superclass for various WAP 2.0 document types. MobileProfilePlugin
extends WAP20Plugin and it is intended for serving XHTML Mobile
Profile 1.0.

Feature support for document types like WML 2.0 or WAP Push should be
created as seperate plugins and quite possibly extend WAP20Plugin.
