Remarks:
When enabled, care must be taken as to what is stored in Annotation field. For example, the annotation string should not be used to store a set of measurements relating to biometric information together with a document checksum, hash, or receipt, and the claimed identity of the user. It should also not be used to store a reason for signing or a statement of importance of the signature in relation to a document. One reason to avoid this is that a conflict may occur between the statement and the contents of the document. The annotation can be used to save tablet setup parameters like TabletType, signature compression setting, and the logical X and Y settings. Saving the configuration this way is especially useful when different tablets are used in different applications. During signing, the annotation string can be used to display auxiliary information in the vicinity of the signature on the screen, or can be used to display and store the name of the signature box or signer for reference purposes.
