// externalLinks()
// DESCRIPTION: XHTML Strict pop-up links (the standard compliant way)
//
// This function is based on that provided by SitePoint in the article:
// http://www.sitepoint.com/article/standards-compliant-world
// It has been modified to better support the REL attribute, as the original
// function did not allow space seperated values. This one does.
// It has also been extended to show you how you might create sized, positioned
// pop-ups
//
//
// I have included two default values you can use for the REL attribute; as
// follows:
//
// <a href="http://someurl" rel="external">pop-up</a>
// Which acts exactly the same as target=_BLANK used to
//
// <a href="http://someurl" rel="sized">
// this will open a new window 450px by 590px.
//
// You can extend this function by defining your own values for use in the REL
// attribute and defining appropriate actions for that value.
// You can also delete all the comments so it all loads faster ;)
//

// 'Popup windows with XHTML Strict' which can be read at:
