That was part of the post-facto "justifications".  The initial impetus
was the invention of "qualified names" in RDF-XML (a markup mishmash
from happy-go-taggy weekenders).  This required an imprimatur, since
it was part of the W3C Metadata Activity, which at that time Could Do
No Wrong and Could Not Be Gainsaid.  Qnames were a done deal,
essentially by fiat, and it was up to the XML Working Group to cook up
a suitable spec.

The business about name collisions was a remarkable episode in mass
delusion.  The means to avoid collisions were already known from the
ENR TC and the Hytime standard: they just weren't well-known, and once
everyone who mattered was pre-sold on Qnames as the greatest thing
since sliced bread, they remained not well-known for good.

On Stack Overflow, I saw a comment remarking that "XML Namespaces are
cargo-cult programming at its finest."  Very succinctly put.

I still think losing the atomic nature of basic tokens like names of
elements and attributes was a mistake.  But, as James wrote, what's
done is done.  The best we can do now is to ease the transition of
namespaces into obsolescence and eventual oblivion.
