[Plugin: Google Calendar Widget] Patch for invalid XHTML output

I’m working on a website using Google Calendar Widget and I discovered that this plugin was outputting two pieces of invalid XHTML.

First, the loading image did not have an alt attribute specified.

Second, the line <script type=”text/javascript” defer=”true”> is invalid. Instead, it should read <script type=”text/javascript” defer=”defer”>.

This is a diff file for ko-calendar.php:

< echo ‘<div class=”ko-calendar-widget-loading”><img class=”ko-calendar-widget-image” src=”‘ . KO_CALENDAR_URL . ‘/loading.gif”/></div>’;

> echo ‘<div class=”ko-calendar-widget-loading”><img class=”ko-calendar-widget-image” src=”‘ . KO_CALENDAR_URL . ‘/loading.gif” alt=”Loading…” /></div>’;
