But again, that is entirely up to you. Of course, this flexibility with tag names leads to other problems. That is where namespaces come into play. Namespaces Namespaces are described in the root tag. The namespace can be anything you like.
Most people use Web addresses or URLs.
We can use namespaces to separate them, but first we need a root tag. Note that I still use the namespaces, because I am using two address tags. When you have empty tags in XML, you do not have to open and close them without having any elements inside. This tells XML that the tag is empty. This can be used to transfer values inside the tags themselves, instead of giving them an element.
