If this is only used in InputTypeView then it should move there.

Also, it appears that no HTLM Input ever uses 'Blocking' so we might as well
just use None, Passive.

Why do you need to keep this value as a member variable?

Also ": Blocking" does not make much sense here. The value after ':' 
defines the bit size for that variable. In this case you would have
used '2'.
