A number input's numbers are decimals in Avalonia, so they are converted
where they are set. A date is "yyyy-MM-dd" both ways. An expander and a
completion box raise their own events from the parts of their templates, so
they listen to the property instead.
The cases of Prop and On are now PropLabel, OnClick and so on. They are
exported with their types, and as Label, Value, Selected and Click they
took names that a program's own messages want.
The panel is flow and not wrap, which is CML's.
