Yes....
CCS and XML- Browser compatibility is an issue. Here is an interesting tid bit to read and understand.

Running in an Intranet you have control of your environment.
Extranet and Internet are another issue.

XML pages display in IE5. I just tried opening 
http://www.ulink.net/plum/oldHSL/newbFic.xml in Netscape 4.61; first the 
browser attempted to open it in IE, then an error message was displayed 
indicating that the dtd could not be located. So, if your Intranet has been 
using XML, you must be using IE5.
