Hi @saraforslund, You can control the allowed file extensions for attachments at board level (in your case for the TKB board) via Admin console. Go to Community Admin -> Choose the board you would like to apply the setting to  -> System -> File Attachments. Enter the file extensions you would like to allow in the setting ' File extensions for attachments '. If you add .xml here, your authors should be able to add xml file as attachment to articles. Thanks, Srujana. ... View more
