I've researched quite a bit on the tag function but have not seen any real world examples of its usage. At first glance it seemed to be a cleaner method of unsetting and inserting a child block by updating the parent but because the doc has been sparse on the tag description its actual behavior is beyond me.

The idea might have been to query the original node and pass the aforementioned extend node to Varien_Simplexml_Element::extend(), accompanied by moving the original node to a different parent node in the merged layout XML.

I could not find any core code in app/code/core/Mage/Core/Model/Layout* that reacts on extend elements though (opposed to block, reference, action, and remove from the same chapter). So I guess this type of layout update somehow found its way into the documentation, but not actually into any release.

    I plan on marking this as the correct answer as it was what was thought originally but I am leaving it open for 48 more hours to allow the chance for another who may have more insight to magento dev to possibly have another answer. But I suspect it was an unimplemented tag method also as I can't get it to fire in any manner at this point but will have time for testing tonight. – Brian Ellis Jan 29 '16 at 14:19
