Return `true` if the specified `specTable` of the specified `length` has a valid set of command‐line option specifications, and `false` otherwise. Optionally specify `errorStream` to which error messages are written. If no `errorStream` is specified, this method produces not output. See {Valid `balcl::OptionInfo` Specifications} for a description of the validity requirements. The behavior is undefined unless `0 <= length`. Note that `specTable` need not be statically initialized.
