Quint Elf I, Ascended template


I was rereading the quint Elf I book when I came across the Ascended Template on page 95.

under special attacks it mentions that the ascended can cast spells as a Sor. of his character level, in addition to any spell casting he had before ascending and that he can also cast spells from several domains as arcane spells.

Does this mean that he can pick spells as a sorcerer once ascended and use spells on the domain list or are his spells only choosen from the domain lists?

If someone could clear this up, it would be very helpful.

Thanks very much
