What is the meaning of “designated”?

In Words and Phrases, Legally Defined (2nd Ed.), volume 2, page 59, the following definition of “designated” appears; Now what is meant by the word ‘designated’ [in a private Act in which ‘officer’ was defined as meaning every officer ‘designated’ an officer in an established capacity]? ... It is a peculiar word, which is not common in the statute book. What is its ordinary meaning? In my opinion it means ‘described as such,’ or ‘described as an officer,’ in other words, there must be some special description of him as an officer in an established capacity. It may be said that it means described eo nomine; I think it does mean in substance, that he is so designated. It does not mean merely ‘called’. It is something more. ‘Designated’ seems to me to involve the idea of being ‘specially described as’. Newton v. Marylebone Borough Council (1914), 78 J.P. 169, per Channel, J., at p. 171.
