SQLite3 extension

Hi As of PHP 5.4.x, the SQLite3 extension has an undocumented method called createCollation(). I'd like to add it to the docs. I'm just reading through your 'how to submit documentation' docs now for the first time. I added a new file en/reference/sqlite3/sqlite3/createcollation.xml in the online editor. I just copy-pasted sqlite3/createfunction.xml and made the appropriate changes. The preview button doesn't work for it. I assume (but don't know) there's no preview because I can't commit to the real repository, and I'm not working on a local copy. Any tips on how to use the PDOE better? Even without the preview, I can guess that one issue with the page would be that it doesn't have the "available since PHP 5.4" note on it. How would I add that? Thanks, Brad
