Re: [libvirt] [PATCHv5 3/6] domaincommon.rng: Add bootloader, bootloader_arg to os=hvm schema for Bhyve

I understand you created separate bhyvebootloader vs xenbootloader schema rules, so that the Xen case can keep <bootloader> as compulsory for use when <bootloader_args> is set, while for bhyve you allow <bootloader_args> without any corresponding <bootloader>. The actual XML parser meanwhile, always allows <bootloader_args> even when <bootloader> is not set. So I think you don't really need to have the complexity of making the schema provide different rules for xen vs bhyve. Lets just stay simple and keep a single <define name="bootloader"/>element and make the <bootloader> optional to match what the parser actually does.
