The XML Declaration is represented in the message tree by a syntax element with field type 'XML.XMLDecl'.

If the XML declaration is created by the XMLNS parser its name is ‘XMLDecl'. However, when a message tree is being written, the name is not important; only the field type is used by the parser.

The following shows an example of a declaration:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE s1 PUBLIC "http://www.ibm.com/example.dtd" "example.dtd">
