[ZPT] Re: [Zip] Coming changes in page templates

[Florent Guillaume]

+1 from me.

The transition will be quite easy as it's very simple to audit the code
for uses that would fail:

find . -name '*.pt' -print0 | xargs -0 grep 'i18n:attributes="[^"]* '

For example current Plone only has one, and our internal code only has a
few occurences.
