It should be clarified whether this means on DTD parsing or on entity parsing. If it means the latter, what happens to the normal text of the document entity, or is that counted as an "external" parsed entity? The original decision on LF seems to be at http://lists.w3.org/Archives/Member/w3c-xml-sig/1997Sep/0005.html and Liam Quinn explicitly immediately raised the subject of the significance of character references at http://lists.w3.org/Archives/Member/w3c-xml-sig/1997Sep/0020.html Cheers Rick Jelliffe
