Out-Of-Scope and Questionable Requirements
| Description |
Stories
|
| OUT OF SCOPE: encryption is complex, volatile, supported by other standards |

|
| OUT OF SCOPE: IP permissions included explicitly in document |
RLP20, RLP21
|
| IMPACT: why do cuts affect encoding? |
RLP14
|
| IMPACT: why does merging affect encoding? |
RLP15
|
| IMPACT: other than polyphony and figured bass, why relevant? |
ED1
|
| IMPACT: why does this affect encoding? |
ED3
