| | 1 | Describe frame content concept and implement base hierarchy.[[BR]] |
| | 2 | |
| | 3 | Frame contents should be: |
| | 4 | * replaceable |
| | 5 | * non-defined |
| | 6 | * unsupported |
| | 7 | * various kinds(text, audio, video, other)[[BR]] |
| | 8 | |
| | 9 | The user should be able to insert a frame without a content and add it afterward or can change the content when he decides. The content can be unsupported if it was created with non-present plug-in for example. The frame and the content of the frame can be considered as separated parts.[[BR]] |
| | 10 | |
| | 11 | Make base implementation of the frame contents hierarchy. (for example it should be implemented with composition of the frame content in the frame) |
