I've been wondering this for awhile. Do you have to have a separate file on a server that defines the xml tags, and then use them in a page after you've linked to the .xml file or something? (Like how css works)

And it's used for security right? Like if a certain company uses a .xml file and defines some tags, the only people who have the .xml file can read exactly what the tag is, right? How is it used in today's webpages?

Thanks for the responses.
