text: The**idNode**member specifies the ID of the node. This member may not have a value of 
  
  **0**. A value of**-1**indicates that child nodes do not use the**idNodeParent**member to 
  
  specify this node as their parent. Instead, this node can be a parent only by enclosing 
  
  child nodes in the EMF. Multiple nodes can have a ID of**-1**. If the ID is not**-1**, the value is 
  
  unique across the document. 
  
  The**nodetype**specifies the type of structure node. This member is equal to one of the 
  
  values from the**MSODOCEXSTRUCTTYPE**enumeration type. The following table lists 
  
  examples of document structure node types.
