The Signed property is true, if the entire form or one or more sections have been digitally signed. If false, the form has not been digitally signed, or a user has removed all signatures from the form.
InfoPath uses XML Signatures to digitally sign forms.
If a form has been digitally signed, its underlying XML document is placed in a read-only state.
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.
