Invoke the specified accessor on the (non‐modifiable) selection of the specified object, supplying accessor with the corresponding selection information structure. The supplied accessor must be a callable type that can be called as if it had the following signature: ` template <class t_INFO> int accessor(const SELECTION_TYPE& selection, const t_INFO& info); ` Return the value returned from the invocation of accessor. The behavior is undefined unless k_UNDEFINED_SELECTION_ID != selectionId(object).
