John Schneider, Takuki Kamiya: Efficient XML Interchange (EXI) Format 1.0. W3C Working Draft 19 September 2008. W3C, 19. Dezember 2008, abgerufen am 7. September 2009 (englisch): „Unlike the optional EXI cookie that MAY occur to precede this field, the presence of Distinguishing Bits is REQUIRED in the EXI header. It is used to distinguish EXI streams from text XML documents in the absence of an EXI cookie. This two bit sequence is the minimum that suffices to distinguish EXI streams from XML documents since it is the minimum length bit pattern that cannot occur as the first two bits of a well-formed XML document represented in any one of the conventional character encodings, such as UTF-8, UTF-16, UCS-2, UCS-4, EBCDIC, ISO 8859, Shift-JIS and EUC, according to XML 1.0“

September 2009 (englisch, Editorial note): „The integration of a magic cookie is under consideration by the EXI WG. A magic cookie would allow distinguishing an EXI document from formats other than XML or from future character encodings“
