Root element
You can change the name of the root element, add attributes and children, and
insert comments, instructions, and, if they do not already exist, XML and/or
document type declarations before it.
Changing the name of the root element changes the name of its start and end
tags. You can change the name using the Edit menu item, or in the Element
Attributes dialog box. Changing the name of the document type declaration, if
it exists, also changes the name of the root element, and vice versa. The root
element name is always the same as the document type declaration name.
You can add the following kinds of children to the root element:
•Elements
•Text
• Control references
• DataWindow expressions (including column references)
• CDATA sections
• Comments
• Processing instructions
