I searched the spec for discussion of delimited binary, scanning, and escaping. I can find really only 2 places where a clarification is appropriate and would be helpful: The definition in the glosssary: *Delimiter scanning* - When parsing, the process of scanning for a specific item in the input data which either marks the end of an item or the beginning of a subsequent item. Delimiter scanning also takes into account escape schemes so as to allow the delimiters to appear within data if properly escaped. changes to (wording change in blue) *Delimiter scanning* - When parsing, the process of scanning for a specific item in the input data which either marks the end of an item or the beginning of a subsequent item. Delimiter scanning of text representations also takes into account escape schemes so as to allow the delimiters to appear within data if properly escaped. Section 12.3.2.2 Delimited Binary Data This section is extended to include: Delimited binary data may have initiators, terminators, and separators in any supported encoding however escape schemes are not available for delimited binary data.
