The spec is a little > ambiguous, isn't it? A little informal perhaps, but I wouldn't have said it was ambiguous. But I'm forwarding this to the public comments list as a request for the spec to be clarified. Suggested wording: The normalize-space function returns a string that is constructed by applying the following changes to the argument string repeatedly until the string is unchanged: * if the string starts or ends with a whitespace character, that character is removed from the string * if the string contains two adjacent whitespace characters, that pair of characters is replaced with a single space character (Unicode x20) Michael Kay XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
