In answer to your question, Sigurd - the asterisk indicates that that attribute is required for that elements (as opposed to optional). For example, if you use the <img> you MUST include a SRC and an ALT attribute for it to be valid.

As an example, with the img element in xhtml 1.1, the attributes 'src' and 'alt' are both marked with an asterisk. Why? http://www.w3.org/TR/xhtml-modularization/abstract_modules.html#s_imagemodul e (I realise img is marked to be deprecated in xhtml2, but I feel adoption for that will require new browsers to come out and gain market share, as the object tag has a huge set of problems) Finally, is there a commentary somewhere about the use of longdesc vs alt vs title (e.g. on images, on images where they are the sole content of links, etc). There seems to be a bit of information here and there, and obviously I can use common sense, but was wondering if there was some high-calibre writing out there, spelling out the different browser support and an overall conclusion?
