They do have a value -- they have whitespace-only text, which is considered
significant unless there is a DTD or schema that says it's not.  Try
parsing this document to understand the difference:

<?xml version='1.0' encoding='ascii'?>
<dsi:Information xmlns='http://www.w3.org/2001/XMLSchema'
xmlns:dsi='http://www'><dsi:Alarm>toto</dsi:Alarm></dsi:Information>
