A issues on AS cluster based deployment

(1) It seems DAS based deployment is required
(2) However, of DAS based deployment, it requires all deployment realted
war and dtd files specified in the DOCTYPE of deployment descriptors
are local for DAS which could cause issues, such as AM and PS deployment
(3) Another major issues is that:

if 2.3 version DD requires FQ URI then if the deployment architecture
are located in firewall, http://java.sun.com/dtd/ssssss will not be
fetched for vaildation.

if file protocol based dtd specification within DTD, it requires local
file structure on the DAS system
