Domains of attraction

Section 2 discusses domains of attraction and says:

In practice nearly all continuous distributions are in the domain of attraction of some extreme value limit.

Page 12 presents some counterexamples:

Continuous distributions not in any domain of attraction These are hard to construct but they do exist! Here are two examples: (a) Any distribution function with slowly varying tail, for instance $F(x) = 1 − 1/ \log x$ for $x > e$. (b) Consider $F_\delta(x) = 1-x^{-1}\{1 + \delta \sin(\log x)\}$ valid for $x \geq$ some $x_0$, with $|\delta|$ small enough to make it a valid distribution function.

The second example is credited to Resnick (1971) "Tail equivalence and its applications".

Log-normal

The question title mentions the log-normal distribution. Page 12 of the book has another example showing the log-normal is in the GPD domain of attraction.

It might be worth pointing out that this involves a more general version of the Pickands theorem than is given on the wikipedia page currently, which says $\Pr(X-u \leq y | X>u)$ converges to a GPD (with constant scale $\sigma$) as $u \to \infty$. A fuller vesion is that $\Pr(\frac{X-u }{h(u)} \leq y | X>u)$ converges to a GPD for some scaling function $h(u)$. (The first pages of Tawn and Papastathopolous https://arxiv.org/abs/1111.6899 have a nice summary of this.) The example in the book requires $h(u)$ to be non-constant. So I suspect the log-normal only lies in the GPD domain of attraction for the general theorem, and not for the simplified wikipedia form.
