  * <p>Implementations should take care to allow for use of string-based bean names, placeholder

+ * user may wish or need to refer to a bean by name. For example, the {@code TxAnnotationDriven} specification
  * referenced above allows for specifying its transaction-manager reference by {@code String} or by

  * replacement and SpEL evaluation for maximum configurability as well as parity with the feature set
