You are right of course.

However Dawn originally stated that a Character was a "strong entity" while a Colour was not. While I did not agree, this was broadly irrelevant to the point I was making and I did not want to get stuck on the digression. As such I changed my example to reflect this in an attempt to get back on track, so I can only hope this tangential line ends swiftly.

I should have used symbols in my example, that had no semantic loading. You live and learn. Received on Thu May 04 2006 - 17:00:06 CEST
