Liam Wrote: By the way, the April 13th draft mentions in numerous places that the ALT attribute is required for APPLET. This is not the case in any version of HTML. EDITORS COMMENTS Correct. It is supported but not required. We have fixed that. ALSO The discussions on the topic of ALT vs. Alternate Content have been very interesting and are leading us to think that maybe we should say in the guidelines that: 1) use of Alternate Content is the preferred way to make applets accessible when not viewed. 2) for the sake of some old browsers, it is recommended that ALT text ALSO be provided (in addition to but not instead of Alternate Content) 3) Note that the use of APPLET in general is deprecated - OBJECT should be used.) . We are also interested in anyone who has any experience with how different browsers handle and APPLET with both ALT text and Alternate Content. We tried a Java Applet element on Netscape 3.02 with Java Applets turned off and found that it displayed the alternate content but not the ALT text. Specifically after viewing a fake applet which has both alt text and alternate content http://trace.ie.wisc.edu/kaboodle/html/tests/applettest.html ) in netscape 1, 2.02, 3.01 and 4 and opera 3.1 with images not loaded and java turned off (where applicable) the content of the APPLET element is displayed. DosLynx displays the alt-text followed by the content of APPLET (which actually reads quite nicely). The results on Microsoft IE 4.01 are inconclusive as we couldn't tell for sure how to turn applets off. (It seemed to want to run the applet with all check boxes unchecked. How do you turn Applets off in IE 4.01?) Therefore, we are thinking that perhaps we should REQUIRE using content of APPLET no matter what (whether functional or presentational) and RECOMMEND using "alt." Your thoughts and comments on this?
