>Example: I have a table presenting the results of a scientific study; I >want to call out three pairs of columns to talk about in the text, by >presenting them in three different background colors.

If all styles must >go through a stylesheet, I must include a STYLE element (possibly >otherwise unneeded) in the HEAD of the document, define three classes >in it (with the wonderfully significant class names "red," "green," and >"blue"), and then apply those classes to the colgroups. Are they really just "red," "green," and "blue?" Or are they CLASS="first_example", CLASS="second_example", CLASS="third_example". The latter is quite useful to someone reading your paper through a speach synth. The former is not. You may have thought this through, and decided that "red," "green," and "blue" are the most meaningful names you can come up with. But what percentage of the population is that knowledgable about device-independant content presentation? Forcing them to go to the header may trigger some thought about the issue. "Carol, why does HTML force me to declare styles like this?" "Because you are supposed to use meaningful names for your classes so that your documents will be useful to people using display devices you have not thought about." Similarly, HTML's limited formatting commands is a powerful pedagogic tool. In online and offline fora all over the world the question "why can't I make blue text" is answered every day. When it is explained, some respond: "I don't care. I just want to make blue text." Some reply: "Interesting idea. Where can I learn more about this structual markup." Many of today's proponents of structural markup started out this way. When you are trying to move people to a new paradigm, you must make it difficult to slip back into the old one. I would guess that that is why SmallTalk and Java don't have functions, and why ANSI C has strong type checking. The proposed STYLE attribute allows you to do your "red", "green", "blue" thing and still serves this educational purpose. It seems like a good compromise to me. Paul Prescod
