It is partly in the framework, but requires cooperation with the device's
bootloader etc.  I don't know about documentation.

The OTA update facility allows anything in /system (and the kernel, and the
radio, again depending on support in the boot loader) to be updated.

Yes such patches can and do get sent over the air.  This depends though on
the device manufacturer having the full support for OTA updates, and the
carrier for delivering them.  All compatible devices are required to have
*some* way to system software updates, though this doesn't need to be OTA (I
believe the CDD should have details on theses requirements).

Note: please don't send private questions to me, as I don't have time to
provide private support, and so won't reply to such e-mails.  All such
questions should be posted on public forums, where I and others can see and
answer them.
