# `_source_alt`

This field points to the true source Alternative of the page. This primarily exists internally to support the builder. In particular the difference to the `_alt` field is that this one will indicate if an alt falls back to a different alternative. At present pages can only fall back to the `_primary` alternative which will be reflected by this field.

## Example
