The XML declaration statement is a required element of an XML document. It tells the user agent that the document is an XML document and what version of XML it is using. The XML declaration statement is a required part of the XML prolog and must be present to write a well-formed XML document.
An XML schema is a road map for the XML document similar to a Document Type Definition (DTD). Created by the World Wide Web Consortium (W3C), schemas describe the elements and map out the presentation and nesting of XML documents. Essentially, the schema enables all applications to understand the flow of the page and validate the elements.
