After clarifiying some of the issues in regard to the feeds issue, we seem to have resolved most of them.
As mentioned before, IE7 does not parse rss files that refer to a dtd. According to some of the internet source consulted, it would be sufficient to remove the <!DOCTYPE> Statement with the named reference. …..so we did.
RssInterface.py was modified accordingly and copied into the RSSINTERFACE Product folder, WISE restarted and voila…
The WISE Site now lists all present feeds under IE7´s RSS Button and a selected feed is parsed with the option to subscribe to it.
