The DOCTYPE declaration must be positioned after the XML declaration and before the root element of the XML document. This informs the parser about the rules that the document must obey, and enables it to validate the document's contents against the specified DTD. Positioning the DOCTYPE declaration at any other location within the document will result in errors and validation failures.
