Implication of the Lock dictionary

Hi Forum, Hi Leonard :-)

I have a question regarding the Lock dictionary of a signature field.

Per definition it "[...] specifies a set of form fields that shall be locked when this signature field is signed."

1.)

Locking means that the annotation flag (F) at bit position 8=Locked of a formfield is set?

2.)

Does it include to set the LockedContents, too?

Thanks,

ToM
