Within this document, the attributes and child elements that may be used within a particular element are typically documented using tables, one table listing attributes and another listing child elements. The order that the attributes are listed within the tables is not significant; they may appear in any order when used within the associated element. However, unless otherwise noted, the order that child elements are listed within the tables is significant; when used within the associated element, child elements must appear in the same relative order as they appear within the tables.
