After a discussion on IRC, I have hope that the textual changes proposed in http://www.w3.org/mid/20060126021444.GZ17752@w3.org will address your concearns. I would like to add that I prefer to define SPARQL characters in terms of Unicode rather than in terms of XML, which are, in turn, defined in terms of Unicode. -- -eric office: +81.466.49.1170 W3C, Keio Research Institute at SFC, Shonan Fujisawa Campus, Keio University, 5322 Endo, Fujisawa, Kanagawa 252-8520 JAPAN +1.617.258.5741 NE43-344, MIT, Cambridge, MA 02144 USA cell: +81.90.6533.3882 (eric@w3.org) Feel free to forward this message to any list for any purpose other than email address distribution.
