Because these standards are not to be fiddled with. VAR elements are typically styles in italics, and depending on your styles it can be anything from virulent green to preformatted text, to help denote the variables you are referring to. > Although html 1.0 never really existed as a standard since then > <var> is defined as simply A variable name. > http://www.w3.org/MarkUp/draft-ietf-iiir-html-01.txt > > As far as I know <var> hasn't changed since then. The XHTML2 specs gives the following example: The parameter <var>ncols</var> represents the number of colors to use. And the HTML5 specs provide the following example: <p>If there are <var>n</var> pipes leading to the ice cream factory then I expect at <em>least</em> <var>n</var> flavours of ice cream to be available for purchase!</p> > <var> is regarded as a Metasyntactic variable > http://www.gnu.org/software/texinfo/manual/texinfo/html_node/var.html > http://www-fs.informatik.uni-tuebingen.de/~hunszing/QuickRef.html You didn't provide the QuickRef information from HTML 1.0 for a ``metasyntactic'' variable, where the user is to replace the variable with a specific instance. Typically displayed in italics. The wikipedia article about metasyntatic variables says A metasyntactic variable (pronounced /ˌmɛtəsɪnˈtæktɪk ˈvɛəriəbl/) is a placeholder name, or an alias term, commonly used to denote the subject matter under discussion It also says about them it has been plausibly suggested that the real reason for the term metasyntactic variable is that it sounds cool > yes it has proved to be useful in programming but that is not its sole > purpose, all it means is this is the bit we want to do something > with...? In all cases of a variable, the purpose of a variable is to be replaced with a specific instance. The Wikipedia article helps to boils this down. There are three specific domains for variables: - computers and maths - physical sciences and engineering - statistics It then goes on to state that in general Variables are used in open sentences. For instance, in the formula x + 1 = 5, x is a variable which represents an "unknown" number. 2:23 is about as far away as we can get from an unknown number. You're going to have a very large uphill battle convincing anyone that the duration of 2 minutes and 23 seconds is a variable. -- Paul Wilkins _______________________________________________ microformats-discuss mailing list [email protected] http://microformats.org/mailman/listinfo/microformats-discuss
