I see, you had to dynamically parse it by implementing
read*FromMessage ad-hoc functions as the nature of that case is
inherently dynamic.

Thank you for the example, I hope your mail will surface in the
Internet search results when the next dev starts scratching the
head. And then probably sdbusplus API will be extended to cover the
usecase if it's needed by more than bmcweb.
