Neither Chrome nor Safari display xml files in browser window. One needs to
select View Source in Safari, to view content of xml files. Where this is
important in Glassfish, is when user tries to view WSDL file from Admin Console,
of a deployed web services application. The file shows fine in Firefox.
Thus we should warn users in the web services section of documentation, that
they will not see WSDL file in Safari nor Chrome, when they click on the link to
the file from Admin Console.
