title: Z-index into xml for Google maps with custom markers
body: <p>I am tring to introduce z-index to my map so I can stack custom markers (<a href="http://www.ghd.com/global/locations/canada-1/" rel="nofollow">http://www.ghd.com/global/locations/canada-1/</a>)</p>
  
  <p>I have read there are properties that exist in v3 that allow this to be set. I am wondering in the short term how to create function that means that property can than be specified in my xml for my example above.</p>
  
  <p>I have seen exmaple where it is set in the javascript, but in this example the markers are all set there as well (<a href="http://econym.org.uk/gmap/zindex.htm" rel="nofollow">http://econym.org.uk/gmap/zindex.htm</a>)</p>
  
  <p>I realize this is probably quite a basic solution, I am not that advanced in javascript unfortunately. Any assistance would be appreciated.</p>
