This page provides checklists for specification developers, editors and reviewers who want to take account of internationalization issues during the development of a spec. Where a checklist item is followed by a more link, click on that for more information. The page also lists links to useful resources on the W3C Internationalization Activity site and elsewhere that may help.
Use of this checklist doesn't remove the need for a formal review, but using it for a self-review can warn of potential issues and requirements, at an early stage, that might otherwise be overlooked. Therefore, the later review should yield few, if any, nasty surprises. It also provides a useful set of points for reviewers to follow.
Interactive checklists! If your spec is github based, you can now create a snapshot of the checklist items in markdown. If you add that to a github issue, you can check off items that are ok, and add comments while doing a self-review. Generate the code here.
