In IE9 Preview 4 we have implemented support for HTMLOptionElement.text by following this requirement. We have discovered that it causes interop issues related to whitespace on existing content on the web. Other browsers do not follow this behaviour. We propose that "The text IDL attribute, on getting, must return the same value as the textContent IDL attribute on the element" be replaced as follows: The text IDL attribute, on getting, must run the following algorithm: 1. Let value be a concatenation of the data of all the descendant text nodes of the option element, in tree order 2. Replace any sequence of one or more consecutive space characters in value with a single U+0020 SPACE character. 3. Remove any leading or trailing space characters in value. 4. Return value. This change appears to be compatible with current browser implementations. 38857 1 ian 2010-09-10 22:39:02 +0000 EDITOR'S RESPONSE: This is an Editor's Response to your comment.
