SdlNativeData	nativeData (SdlNonConstInstance instance) const override

Empty native data info will be returned in cases where this field is not owned by (or being part of) the input instance. Obtaining native data requires the input instance be valid during this call and any further usages of the returned native data.
void	fromSdl (Owner &owner, const SdlInputClause &clause, const SdlInputContext &ctx) const

void	loadFromSdl (Owner &owner, const SdlInputClause &clause, const SdlInputContext &ctx) const override=0
	Load SDL value to actual value and store it in the owner's field. Implementations are highly encouraged to throw SdlLoadError if the loading process is not successful. This will allow things such as automatic fallback to work according to field policies.
void	saveToSdl (const Owner &owner, SdlOutputClause &out_clause, const SdlOutputContext &ctx) const override=0
	Convert actual value back to SDL value. Saving a loaded value as SDL value should rarely fail–as loaded value has been properly handled by the loading process already. In case of failure, throw SdlSaveError and provide detailed reason describing the event.
