title: Why XSD spec accepts timezones having -14H?
body: <p>I was playing around with some dateTime functions in xquery, and I've noticed that xquery accepts dates with timezones having -14 hours.</p>
  
  <p>Looking at wikipedia <a href="https://en.wikipedia.org/wiki/List_of_UTC_time_offsets" rel="nofollow">link</a> I can see the minimum allowed timezone is -12H, but the <a href="https://www.w3.org/TR/xpath-functions/#component-extraction-functions" rel="nofollow">xpath functions</a> seem to allow -14H. Am I missing something?</p>
