Also the forward slash is definite required to remove any syntactical ambiguity.
"<purchase>
 </purchase>
 <purchase>
 </purchase>", if without "/", becomes identical to

<purchase>
   <purchase>
   </purchase>
</purchase>

Its clearly a completely bogus principle!  In fact, for markup languages
the reverse is true: having more forms makes data capture and modeling 
easier because you can choose the form that requires the least work. 
E.g. (<![CDATA[ ]]> or  &amp; ) and (element or attribute) and
(<x></x> or <x/>) and ( y="z" or y='z'). 

The other bogus principle is that there should only be one syntax for 
everything.
Looking at the triumph of the C family over the LISP family, it is more
likely that people prefer a variety of embedded syntaxes which serve to indicate 
semantics or role graphically.
