CustomXMLParts Object (Office)
Represents a collection of CustomXMLPart objects.
Remarks
There are three default parts that are always created with a document. These are 'Cover pages', 'Doc properties' and 'App properties'. The last two were in previous versions of Microsoft Word but are now provided in XML form in the CustomXMLParts object collection
Example
The following example adds a node to a CustomXMLPart object that is part of the CustomXMLParts object collection.
Sub AddPartToCollection()
Dim myPart As CustomXMLPart
Set myPart = ActiveDocument.CustomXMLParts.Add("<author>Mark Twain</author>")
End Sub
