This feature is implemented as a string that can range from "none",
"aplic" and "aplic-imsic".
If the feature isn't present in the domain XML the hypervisor default
will be used. For QEMU, at least up to 9.2, the default is "none".

This needs to be changed to 11.1.0, sorry for missing this patch for so long. Also, the hypervisor default will be used even the user specifies aia='none' based on the code in patch 3/3. So either we need to add an absent value for this attribute or change the wording. Other than that these patches are all fine and good to go, the only thing above needs to be figured out.
