[Plone-docs] Document Plone 3.3 PLIPs when needed

[I. S. P. <duk...@gm...>]

I've filed some bugs in Trac on the documentation component regarding Plone
3.3 accepted PLIPs
documentation<https://dev.plone.org/plone/query?status=new&status=assigned&status=reopened&component=Documentation&milestone=3.3&order=priority>
.

AFAIK, neither we (the doc team) nor the framework team have defined a
specific workflow to document PLIPs but both seem to agree this is
necessary.
