Subject: [PATCH] Annotation - Checkboxes with the same name and export values
 must be in unison   - it aims to fix #14024.   - this patch adds an attribute
 `acroformExportValue` to the HTML input in order to set the checked attribute
 in taking into account the exportValue for the checkboxes with the same name.
