Maybe: <hugepages> <size strict='yes' unit='G'>1</size> </hugepages> where strict could be no if we are giving a hint but don't care if the hint cannot be honored (default yes if omitted), and where unit + value allows the user to input the size in a sensible unit (on output, we'd probably want to use unit='k' and spell out 1048576, for similarity with all our other memory interfaces that output in k for back-compat reasons).
