It appears that it was designed to only support one file extension per mime type. It probably would be better to change cr_mime_types to have a composite primary key consisting of the mime type and the file extension. Such a change would require minor modifications to the following packages:
- acs-content-repository
- bboard
- cms
- cms-news-demo
- download
- file-storage
- general-comments
- photo-album
- ticket-tracker-lite
- wp-slim
What is the problem that you're trying to solve?
