The first form is preferable to the second, because using the `idref` tag lets the
container validate at deployment time that the referenced, named bean actually
exists. In the second variation, no validation is performed on the value that is passed
to the `targetName` property of the `client` bean. Typos are only discovered (with most

NOTE: The `local` attribute on the `idref` element is no longer supported in the 4.0 beans

your existing `idref local` references to `idref bean` when upgrading to the 4.0 schema.
