Slice actions is a list of slices that have control over a specific flowspace. This list is comma separated and the slice actions are of the form Slice:slicename1=perm[Slice:slicename2=perm[...]]. Each slice possibly has three types of access permissions over a flowspace, which are 60;DELEGATE, READ, and WRITE. Permissions are currently specified as an integer bit mask value. The assignment is: DELEGATE=1, READ=2, WRITE=4. So, Slice:alice=5,bob=2 would give DELEGATE and WRITE (1+4 = 5) permissions to Alice's slice and only read permissions to Bob.
