XML tags, declarations, and comments

• Each XML tag begins with < and ends with >.
• The first line in an XML document is an XML declaration that indicates which version of the XML standard is being used for the document.
• The declaration also usually identifies the standard character set that's being used. For documents in English-speaking countries, UTF-8 is the character set that's commonly used.
• You can use the <!-- and --> tags to include comments in an XML document.
