I agree.  In fact my argument is that a Namespace URI should be like a
domain name -- it is the persistent, public face of a vocabulary.

Microsoft might restructure their Web site tomorrow, but they'll
probably still keep the microsoft.com domain name so that people can
find the new site. Imagine if you had to choose between the following:

  microsoft-strict-1-0.com
  microsoft-transitional-1-0.com
  microsoft-frameset-1-0.com

And then, after the redesign

  microsoft-1-1.com

then

  microsoft-1-2.com

then

  microsoft-2-0.com

Microsoft can change their IP address and their internal structure as
ofter as they like, but it's hard for people to find them if they
change their domain name.  Likewise, XHTML can change its
DTDs/schemas, but will be very hard for deployed software to recognize
XHTML if it keeps changing its Namespace URI.


All the best,


David
