externalLinks script

-----------------------------------------------------------
Description:
Function that enable external links in standard compliant
web pages. The scripts traverses all the anchors on a web
page and enables anchors with a rel="external" to open a

however this attribute does not comply with W3C standards
for XHTML.

Simply place a link to the this script in the head-section
of the XHTML page. The script will then automatically
execute on page load.

<script type="text/javascript" src="externalLinks.js"></script>

-----------------------------------------------------------
Example:
<script type="text/javascript" src="externalLinks.js"></script>

<a href="http://www.ebound.dk" rel="external">this link
 opens the ebound website in a new window</a>

-----------------------------------------------------------
Dependencies:
This script depends on the windowOnLoad-script to execute
