ID for this document element, specified as a character vector or string scalar. The DOM generates a session-unique ID when it creates the document element. You can specify your own ID.

Source DOM object from which the message originates.

Tag for this document element, specified as a character vector or string scalar.

The DOM generates a session-unique tag as part of the creation of this object. The generated tag has the form CLASS:ID, where CLASS is the object class and ID is the value of the Id property of the object. Specifying your own tag value can help you to identify where an issue occurred during document generation.

Message text, specified as a character vector.
