The answer turned out to be a simple one. Just one look at the info sent by email by the gentleman was enough. Here is what he was viewing in his browser:
local news, travel, and all the essential information for people wanting to
visit Tarbert and the surrounding areas in Argyll, Scotland" />
local festivals, local info, business, history, travel, lochgilphead,
ardrishaig, argyll, loch fyne, scotland, TARBERT" />

The question is: Why win 98, IE 6.0.2800.1106 should throw up the page as xml file whereas the other IE versions were able to view the page properly?
However, to keep IE 6.0.2800.1106 happy one has to make sure the lines of code stay in their proper position. The problem is more likely to occur if one converts the code into a template and then tries to enter Description and Keywords.
