The prolog, short for "processing instruction and document type declaration", is the portion of an XML document that contains processing instruction statements (such as specifying the version of XML being used) and any additional comments necessary to provide information about the document's content and structure. It precedes the actual content of the document. Schemas and relations are not specific parts of an XML document, and a declaration, though related, is not the proper name for this portion of the document.
