Invoke the specified accessor on the (non-modifiable) selection, 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& refOrValue, const t_INFO& info); ` Return the value returned from the invocation of accessor. The behavior is undefined unless selectionId() != -1.
