Recently, I made a typo and left out the slash in an end tag (on the 
tag soup side). Since Gecko forces tag soup into a tree, I didn't 
notice anything in Firefox. However, in IE my script produced 
exceedingly weird results. It turned out that IE had created a non-tree 
DOM and my single typo had multiplied thanks to cloneNode preserving 
the non-treeness. It would have saved me debugging time if I had seen a 
parse error message up front.

 From the "tools will save us" point of view, you need a text editor 
that tries to parse the doc using an XML parser when you intend to 
write XML.
