The reason I was suggesting to introduce a new statement
(<browse2:page>, <browser:publish>, ...) with the intent to later
deprecate it, was the lack of good notation, at least something
that is as good as the original <browse:page>, that is after
all how this dicussion thread started.

If everyone is fine on this list that <browser:publish> is just as
good as <browser:page> then I can certainly live with that for a
longer time - Philipp expressed some concerns in this thread though
(http://mail.zope.org/pipermail/zope3-dev/2006-April/019229.html).

I was just suggesting a possible way to allow for a smooth
transition and in the long run to aim for the best notation
possible. - I am certainly open for discussion though what
that best notation is.

To stress the comparison with the Python language once more
and to give a concrete example:
  In Python 2.x we have range() and xrange() 
  In Python 3.y we will have range() with the meaning of the former xrange()
That is because xrange() is the better function and range()
is the better (simpler) notation.

See above.
