An export/import facility for tests be allow editing in another editor
This would allow the test to be edited with any common mass update facilities, without having to include them in LC.
The import facility could then perform a validation to ensure that the test was compatible with the proprietary rules in LC and the tests could be used in their updated states.
The validation routine could then add stamps to indicate:
1. It has been edited with ... <tool name>, date time stamp and reference the original test.
2. A Label to allow brief notes on what was done
3. A flag to indicate it has been externally edited,
Not all required, but these would help in mixed test environments.
Alternatively: Make tests editable with other editors directly (probably more difficult, and with less control of content).
