I doubt there are many rendering engines that would be specific to one type, othewise something like this wouldn't be possible: <img src="blah.gif" alt="Look, it's an image" /> You can use numeric character references instead of quotes if you like. tpgc> In a lot of cases, as long as there are no spaces involved, you tpgc> can go without the quotes too but that's just really poor coding tpgc> practice I think. >From the spec: "In certain cases, authors may specify the value of an attribute without any quotation marks. The attribute value may only contain letters (a-z and A-Z), digits (0-9), hyphens (ASCII decimal 45), periods (ASCII decimal 46), underscores (ASCII decimal 95), and colons (ASCII decimal 58). We recommend using quotation marks even when it is possible to eliminate them." Bear in mind this is the HTML 4.1 spec - the XHTML spec is vastly different and non-quoted attributes will fail validation big time.
