Notes
|
||||
-----
|
||||
|
||||
Regarding the AVISPA IF report:
|
||||
|
||||
- Messages do not seem to contain Varable' as an option, seems to be
|
||||
flaw in the BNF.
|
||||
- State has no BNF definition in the second half, it seems.
|
||||
- Is Fact well-defined?
|
||||
- Authenticate has no parameters in it (only constants)
