Hi Tres,
Thanks for the great idea!
I'm a zpt and zope newbie, so please forgive my ignorance. Does what
you recommended mean that if I have no need for a 'real' tag, I can
create and use a 'tal'-based tag like you did in your example? Does
the element 'loop' have any special meaning?
It seems as if using 'div's and 'span's just to hold tal directives is
not a great idea (even if they can be 'omit-tag'ged away), or am I
missing something?
Although I am reading as much as I can about zpt, I seem to be missing
a lot of important stuff.
Cheers,
gyro
