+According to the HTML specs, "area" and "a" elements are allowed inside of a "map".
+Both can have a "coords" attribute, but "area" elements can't contain child nodes.
+To have regions with content use "a" tags, e.g.
+
+<map class="dl-keep dl-regioncontent">
+   <a href="http://www.mpiwg-berlin.mpg.de" coords="0.4907,0.3521,0.1458,0.107">
