Because otherwise the 'no' layout is treated as disagreement with whatever is to
be disagreed with. Fixed in YAML 1.2 but that's not universally supported.
Fixes#268
We have a lot of keyboard layouts and the current output format is virtually
useless at searching for a specific one to debug any issues with either the
layout list or the output from libxkbregistry.
Let's use YAML instead because that can easily be post-processed to extract the
specific layouts wanted, e.g. to get the list of all layouts:
xkbcli-list | yq -r ".layouts[].layout"
to get the list of all variants of the "us" layout:
xkbcli-list | yq -r '.layouts[] | select(.layout == "us") | .variant
and the number of option groups:
xkbcli-list | yq -r '.option_groups[] | length'
Note that the top-level nodes have been de-capitalized, so where it was "Models"
before it is now "models" and the "Options" node is now "option_groups".

This library is the replacement for clients parsing evdev.xml directly.
Instead, they should use the API here so that in the future we may even
be able to swap evdev.xml for a more suitable data format.
The library parses through evdev.xml (using libxml2) and - if requested -
through evdev.extras.xml as well. The merge approach is optimised for
the default case where we have a system-installed rules XML and another file in
$XDG_CONFIG_DIR that adds a few entries. We load the system file first, then
append any custom ones to that. It's not possible to overwrite the MLVO list
provided by the system files - if you want to do that, get the change upstream.
XML validation is handled through the DTD itself which means we only need to
check for a nonempty name, everything else the DTD validation should complain
about.
The logging system is effectively identical to xkbcommon.
