Requested to add hint definition support to the XLS Form https://github.com/XLSForm/xlsform.github.io/issues/219

For anyone facing this, a `temporary workaround` can be to integrated a direct DB function. Example with above use case, on PostgreSQL: `cb.isNotNull(cb.function("array_position", Integer.class, filter.getVersion(0), root.get("version")))`
