6. It is not good XML -- the x-type tags are not how new tags are added
to XML specifications. The whole point behind XML is to be able to add
new elements at a later point in time, and using x-type tags is not
using XML's best features.

--> The x-Tags aren't about just adding new tags. The point is to make a
distinction between standard accepted tags which could be used by 
else for something useful, and your own "personal data" tags. For 
example, I
doubt anyone else would care what the value of the x-Yahoo-ID tag is 
Yahoo. However, if someone added a <Mood> tag, other people might want 
use that as well.
