XML is derived from SGML, and so was HTML. So in essence, the current infrastructure available today to deal with HTML content can be re-used to work with XML. This is a very big advantage towards delivering XML content using the software and networking infrastructure already in place today. This should be a big plus in considering XML for use in any of your projects, because XML naturally lends itself to being used over the web.
Even if clients don't support XML natively, it is not a big hindrance. In fact, Java with Servlets (on the server side) can convert XML with stylesheets to generate plain HTML that can be displayed in all web browsers.
Using XML to pass parameters and return values on servers makes it very easy to allow these servers to be web-enabled. A thin server side Java layer might be added that interacts with web browsers using HTML and translates the requests and responses from the client into XML, that is then fed into the server.
