//! `DynamicDataOptions` (`DynamicDataOptions.cs`): the defaults of the options of the binding
//! operators, which an application may change.
//!
//! Deviation (DEVIATIONS.md, DynamicData): upstream's static properties are global; the port's are
//! per thread, as its observables are (docs/porting/reactive.md, section 5.1).
