OperationPermission should be able to include more than one Permission

It seems silly that a Permission which allows everything except DeleteFile and ReplaceFile has to look the following:

<OperationPermission>
<Operation>GetFileIDs</Operation>
</OperationPermission>
<OperationPermission>
<Operation>GetFile</Operation>
</OperationPermission>
<OperationPermission>
<Operation>GetChecksums</Operation>
</OperationPermission>
<OperationPermission>
<Operation>PutFile</Operation>
</OperationPermission>
<OperationPermission>
<Operation>GetStatus</Operation>
</OperationPermission>
<OperationPermission>
<Operation>GetAuditTrails</Operation>
</OperationPermission>

It would be much simpler if all the operations could be defined within one OperationPermission:

<OperationPermission>
<Operation>GetFile</Operation>
<Operation>PutFile</Operation>
<Operation>GetChecksums</Operation>
<Operation>GetFileIDs</Operation>
<Operation>GetAuditTrails</Operation>
<Operation>GetStatus</Operation>
</OperationPermission>
