Is a sorcerer with the domain-access alternative class feature considered both an arcane and a divine caster?

The alternative class feature Domain Access (Complete Champion, p. 52) reads, in part:

Choose one cleric domain. If you worship a specific deity, the domain you choose must be one to which your deity grants access. You gain the granted power of the chosen domain. In addition, you can cast one domain spell of each spell level available to you per day from that domain.

Does having access to the domain spells make a sorcer qualify for any prestige class that requires the PC to be a divine caster?
