Subject: Re: [docbook-apps] sub equations
Hi Chris, You didn't mention whether you wanted to change the structure of the equation element to support sub equations, something like nesting equation elements. If that isn't necessary, and if the sub equations are separate, you could just create a stylesheet customization to respond to a role attribute on an equation that designates it as a sub equation. In other words, if it is just a labeling issue then the stylesheet could do it. Perhaps using role something like this: <equation id="main-one"> ... <equation id="sub1" role="subequation main-one"> ... The first word in the role attribute identifies the second equation as a sub equation, and the second word provides the id of the main equation. Then the stylesheet could form a number label based on that information. The number label would come from a customization of the template in common/labels.xsl that starts with: <xsl:template match="equation" mode="label.markup"> Copy that to a customization layer, and change the match to: <xsl:template match="equation[starts-with(@role, 'subequation')]" mode="label.markup"> and then change the template could parse the role value to get the id of the main equation, and form the number label.

I have never extended the docbook dtd or stylesheets, and know it would be a large undertaking for myself. I was wondering if anyone has already implemented this modification - have you? please speak up :] It is probably a modification that an engineer would make, rather than a mathematician... we're always coming up with sub equations that are actually not so important...
