ID for this document element, specified as a character vector. 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 the document element, specified as a character vector.

The DOM generates a session-unique tag when it creates the document element. Structure the tag as class:id, where class is the class of the element and id is the value of the Id property. You can specify a tag to replace the generated tag. Specifying your own tag can make it easier to identify where an issue occurred during document generation.

Message text, specified as a character vector.
