Unless the CSS is specifically designed to be processed by a non-graphical medium (unlikely) then all that a non-graphical renderer has to work on is the XML element types. Since those cannot be known in advance, the end-user must construct a new stylesheet for every document type -- that's a high price to pay for reading a single document! HTML has the virtue that it has a set of "formatting objects" that we know can be rendered both graphically and non-graphically. We also know HOW to render them non-graphically *in advance*. An arbitrary XML document type does not have that virtue. Formatting objects are not as bad as arbitrary XML -- at least they are known in advance. But as Hakon pointed out, they are probably not as good as HTML -- they aren't designed for multiple media display. -- Paul Prescod - ISOGEN Consulting Engineer speaking for only himself http://itrc.uwaterloo.ca/~papresco "The Excursion [Sport Utility Vehicle] is so large that it will come equipped with adjustable pedals to fit smaller drivers and sensor devices that warn the driver when he or she is about to back into a Toyota or some other object." -- Dallas Morning News XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
