            A
            
             
              string
             
            
            value
that represents the type of changes that an end user can perform
on a PDF document without invalidating the certification signature.
It is used in the
            
             Certify PDF operation
            
            operation of the Signature service. These string values
are valid:
            
           
            - 
             FormChanges:
            
 
            - 
             The end user is permitted to fill in the form, instantiate
page templates, and sign the form.
            
 
            
             
            - 
             AnnotationFormChanges:
            
 
            - 
             The end user is permitted to fill in the form, instantiate
page templates, sign the form, and create annotations, deletions,
and modifications.
            
 
            
             
            - 
             NoChanges:
            
 
            - 
             The end user is not permitted to change the form. Any change invalidates
the signature.

              No Changes Allowed:
             
 
             - 
              No changes to the document are permitted. Any change invalidates
the signature.
             
 
             
              
             -
