Because when XML was pulled together in the mid-1990's it was made to 
be an application of SGML from the early-1980's (retroactively 
modified a bit to accommodate some of the decisions made in XML).

Such a decision would have made an instance of XML not an instance of SGML.

And just because something is unambiguous doesn't make it meaningful 
to implement.

I hope this helps.
