# has_standard_alternative

A Boolean value that specifies whether this element has a standardized alternative.

For standardized elements, this method always returns `false`.

For non-standard elements:

- When this value is `true`, this element contains metadata that also exists in a standardized element in the same Metadata object. The standardized element might present the metadata with different units.
- When this value is `false`, no standardized alternative exists.

## Syntax

    bool has_standard_alternative() const;
