I was about to correct you with the namespace used for the 
'traversalNamespace' directive as number 10, but I just found out that 
directive is added into the main Zope namespace.  But for the last 
three days, I thought otherwise.

To my eyes (and I again I raise the "I may just not be acclimated to 
XML" flag, partly because I like saying 'acclimated' almost as much as 
I like saying 'indefatigable') this::

<zopeConfigure
    xmlns='http://namespaces.zope.org/zope'

and this::

<zopeConfigure
    xmlns='http://namespaces.zope.org/help'

are not easily distinguishable when staring at a ZCML file too late at 
night, especially when there are other namespaces being registered (and 
what if 'page' shows up in more than one namespace?  And if that's not 
going to happen, then why have namespaces?).

Maybe I've just gotten used to the concept that 
'namespaces.zope.org/zope' is always going to the primary namespace 
(especially with the zopeConfigure tag there).  I can learn my way 
around this though.
