| 3 | * Saving a wiki page created using ContentTranslation. |
| 4 | * The following special things happen when the page is created: |
| 5 | * - HTML from the translation editor's contenteditable is converted to wiki syntax using Parsoid. |
| 6 | * - A change tag is added. CX2 uses an additional tag. |
| 7 | * - The edit summary shows a link to the revision from which the translation was made. |
| 8 | * - Optionally, a template is added if the article appears to have a lot of machine translation. |
| 9 | * - Categories are hidden in <nowiki> if the page is published to the user namespace. |
| 10 | * - Information about the translated page is saved to the central ContentTranslation database. |
| 11 | * - When relevant, values of MediaWiki CAPTCHA can be sent. |
| 12 | * - When relevant, Echo notifications about publishing milestones will be sent. |
| 13 | * This borrows heavily from ApiVisualEditorEdit. |
