Namespaces create confusion by seeming, to the naive, to accomplish
things that only architectural forms (AFs) actually accomplish.
Namespaces occupy scarce public mindspace with a "solution" that is
still being promoted as solving problems that it does not, in fact,
solve.  So, it's only *in reality* that XML Namespaces get in the way
of using AFs.

Ignorant claims made for XML Namespaces are creating messes.  When the
cleanup bill comes due, it will not add to the credibility of XML.

Jeez, Tim, you're just about to say that AFs solve problems that XML
Namespaces don't solve, but first you're complaining that AFs have a
more complicated syntax.  Why are we supposed to believe that this
extra complexity is bad or unwarranted?  As for the syntax of AFs
being "ugly", what you seem to be saying is that AFs were rejected on
account of the esthetics of the ISO syntax for expressing them.  Do
you really mean that?  Are your esthetic sensibilities so infallible
that they should act as guiding design principles for the information
economy of the entire planet?  And even if that were true, why can't a
syntax guru like you design a prettier syntax that offers the same set
of vital functionalities?

Thanks for this potshot, Tim.  It honors my efforts to sensitize our
readers to the question of who wins and who loses whenever a decision
is made to adopt (or not to adopt) the architectural forms paradigm.
