EditSection can be used the edit the patient information through the patient dashboard with the given configurations. Most of the time, We used the editSection to edit the Contact Information. So the success info message was fixed to show like "Saved changes in contact info for: PatientName".
See here: https://github.com/openmrs/openmrs-module-registrationapp/blob/5ac4b5f900237168b720b3613f91adc2fa8e87ad/omod/src/main/java/org/openmrs/module/registrationapp/page/controller/EditSectionPageController.java#L150
It should be improved to support to the info message with other custom fragments.
Dev Notes :
Add a fix to support the info message as "Saved changes in <section Label> for: <PatientName>", if the sectionId is other than the Contact Info.
Eg : Saved changes in Access Location Info for: HarishRam
