In this earlier thread titled 'Can I precede a noun with more than one determiner?', the most-voted answer by Barrie England says:
Yes, more than one determiner can precede a noun, but they do so in a particular order. All, both and half come before articles, so your example would have to read I saw two cats this morning. Both the cats were very young (but in this case the can be omitted).
At first blush, this answer may seem to have already addressed my question, but that is not so, because it failed to distinguish the difference between a determiner (function) and a determinative (category), in part because it wasn't clear whether the question itself was about the former or the latter.
For this distinction, please see this earlier question 'Determiner vs. Determinative' and its answer.
According to this distinction, I think that, when coming before articles, all, both and half are not determiners but predeterminers, and that both in both cats were very young is a determiner.
Against this backdrop, I'd like to ask basically the same question with this determiner/determinative distinction in mind. And I'm not asking about 'determinative' (lexical category), I'm asking about 'determiner' (grammatical function).
With regard to the 'both the' example of the earlier question, I will say that you have only one determiner (function) and that is 'the', with 'both' being a predeterminer.
Does this mean that there can be only one determiner (function) that precedes a noun, in general?
How about this example?

Are both 'another' and 'three' determiners (function)? Or is only one of them a determiner (function)? If so, which one is the determiner?
