Remarks
If the IsSigned property is true, the form has been digitally signed. If false, the form has not been digitally signed.
InfoPath uses XML Signatures to digitally sign forms.
Note: If a form has been digitally signed, its underlying XML document is placed in a read-only state.
Important: This member can be accessed only by forms running in the same domain as the currently open form, or by forms that have been granted cross-domain permissions.
