XML element naming rules

XML elements must follow these naming rules:

• Names can contain letters, numbers, and other characters. Except for the first character, they can contain
  • digits
  • period(.)
  • hyphen(-)
  • underscore(_)
  • colon(:) - legal but should be used except for namespaces
  • NO other characters are allowed like #, @, $, %
• Names cannot start with a number or punctuation character. Must start with a letter or a underscore(_).
• Names cannot start with the letters xml (or XML, or Xml, or xMl etc)
• Names cannot contain spaces

Any name can be used, no words are reserved.
