Why this!? Any distinctive features?
<?dp n="579" folio="579" ?> For what is such an entry good? (I guess and anticipate one of the possible answers: Ask the publisher!)

<?xyz?> is an XML processing instruction (PI),
not a comment; it is intended to give the software which processes the XML some extra information about the document which it MAY either use or ignore. Comments are written <!-- ... --> and MUST BE ignored.
In the case of <?dp ... ?>, the PI provides information about the document page numbering.
