+/**
+ * This class implements Quick Assists for XML files. It does not perform any
+ * quick assistance on its own, but it coordinates the various separate quick
+ * assists available for XML such that the order is logical. This is necessary
+ * because without it, the order of suggestions (when more than one assistant
+ * provides suggestions) is not always optimal. There doesn't seem to be a way
+ * from non-Java languages to set the sorting order (see
+ * https://bugs.eclipse.org/bugs/show_bug.cgi?id=229983 ). So instead of
+ * registering our multiple XML quick assistants via the plugin.xml file, we
+ * register <b>just</b> this manager, which delegates to the various XML quick
+ * assistants as appropriate.
