Indeed, after this series you can use 'limit' everywhere, so there is no real reason for the x- fields to stay. I almost included the removal in this series, but then it turned out that some more test cases depend on it than I wanted to fix up on the side. But it's an obvious follow-up series. Kevin

[PATCH v2 09/31] qapi/qom: Add ObjectOptions for throttle-group
This adds a QAPI schema for the properties of the throttle-group object. The only purpose of the x-* properties is to make the nested options in 'limits' available for a command line parser that doesn't support structs. Any parser that will use the QAPI schema will supports structs, though, so they will not be needed in the schema in the future. To keep the conversion straightforward, add them to the schema anyway. We can then remove the options and adjust documentation, test cases etc. in a separate patch.
