Subdomain choice restrictions

[Bling]

The Sacred Servant gives Paladins the ability to chose a domain from the cleric domains.

Spells:

At 4th level, when a sacred servant gains the ability to cast spells, she also chooses one domain associated with her deity. Her effective cleric level for this domain is equal to her paladin level –3. In addition, she also gains one domain spell slot for each level of paladin spells she can cast. Every day she must prepare the domain spell from her chosen domain in that spell slot.

Can the paladin chose a subdomain as well, or are there restrictions?
Thanks.

If the subdomain is available to the deity, they can take it. They can also take an inquisition instead of the domain if they choose.
