(in XHTML transitional) First, we need to clarify what "you" in "you do not allow the allowtransparency attribute" is. * given that you sent this mail to the mailing-list for the markup validator users, I suspect you first meant "why doesn't the validator accept this attribute". The answer is simple: the validator checks document against the standard grammars, and if the attribute is not in the language, it's not accepted. * the next question obviously is "why isn't this attribute in the standardized language". This question is off-topic for this forum, and I would recommend that you contact the W3C working-group responsible for the XHTML1 recommendation at www-html@w3.org. Just be aware that what gets into a W3C recommendation (and what is left out) is not arbitrary: there is a (long) process of building consensus between all actors involved in the technology (including the browser makers you were mentioning in your message), and a large- scale feedback system whereby anyone is welcome to suggest improvements. And while I am not familiar with how it was decided to leave the allowtransparency attribute out of XHTML1 (after it was added as a proprietary attribute by Microsoft in IE5, if my research is correct), I suspect it was because, as a design principle, (X)HTML elements and attributes are defining semantics, and styling is left to CSS. For more details, please ask the HTML mailing-lists. Thank you. -- olivier
