[libvirt] RFC: "Determine if the domain has been updated."?

Hello, <https://libvirt.org/html/libvirt-libvirt-domain.html#virDomainIsUpdated> states:
int virDomainIsUpdated (virDomainPtr dom)
Determine if the domain has been updated.
dom: pointer to the domain object Returns: 1 if updated, 0 if not, -1 on error
Not very enlightening :-( So what's the meaning of "updated" here: "inactive XML got changed but the currently running VM was started from a different XML"? Only very few drivers seem to mention it at all and they seem to mean different things. Any nobody seems to update the variable, only 4 readers:
$ git grep -ne '->updated' libxl/libxl_driver.c:4844: ret = vm->updated; lxc/lxc_driver.c:343: ret = obj->updated; qemu/qemu_driver.c:1628: ret = obj->updated; uml/uml_driver.c:1456: ret = obj->updated;
