Well, change 'cast-element: paragraph' to 'display: block' and it's not CSS syntax, it *is* CSS. It works very well for mapping a single element to a single display object. But when you extend CSS to create multiple formatted objects, it becomes more complicated. I believe that structured document syntax is natural for representing structured document transformation (using Didier's syntax): <element match="tag"> <paragraph font-size="12pt"> <ancestor name="container"> <descendant name="title"/> </ancestor> <text>: Tag</text> </paragraph> <paragraph font-size="10pt"> <children/> </paragraph> </element> Or, in XSL: <xsl:template match="tag"> <fo:block font-size="12pt"> <xsl:apply-templates select="ancestor(container)/title"/> <xsl:text>: Tag</xsl:text> </fo:block> <fo:block font-size="10pt"> <xsl:apply-templates/> </fo:block> </xsl:template> In DSSSL: (element tag (sosofo-append (make paragraph font-size: 12pt (process-node-list (select-elements (children (ancestor "container")) "title")) (literal ": Tag")) (make paragraph font-size: 10pt (process-children)))) Can you show an example of this in your CSS-transformation syntax? I can't find the proposal, and didn't bookmark it. -Chris -- <!NOTATION SGML.Geek PUBLIC "-//Anonymous//NOTATION SGML Geek//EN"> <!ENTITY crism PUBLIC "-//O'Reilly//NONSGML Christopher R.
