- XML Declaration
- Some information about the file can be passed to the parser in the XML declaration on the first line of an XML file. The declaration starts with <?xml and ends with ?>. Attributes for version, encoding and standalone may be included (in that order only). A sample XML declaration is: <?xml version='1.0' encoding='UTF-8' standalone='yes'?>
- Namespaces
- Categories of elements (a bag of names). Easily get separate by adding a prefix to the element name with a : in between. In order to get rid of the circumstance where namespaces may have the same name, URI's may used: <personnel:title xmlns:personnel="http://lepp.cornell.edu/personnel">. Here the prefix points to the URI in the attribute. If xmlns without a suffix is given as the attribute, that defines the default namespace.
