By combining EWD's "static" and dynamic Ajax techniques, you can create a hybrid application where the Container Page is a static page whose contents can be progressively replaced by both "static" fragments and dynamic EWD Page Fragments. Provided the pages are coming from the same domain, you can even use this technique to get EWD to "parasitise" a Container page that has been delivered and created by another technology entirely.
