.al is mostly sold in domain hacks. For example, cor.al, mur.al and so on.
For this one, I am not sure. maybe xxxx, maybe none.
I am not very much aware of the .al extension. However, looking at the sales on Namebio, although .al is popular in dubai, it looks more popular with domain hacks.
Let's wait for some other appraisals on this one as I may be terribly wrong on this one!!
