Benefit: As a full-round action, you can move up to your speed and make a single melee attack without provoking any attacks of opportunity from the target of your attack. You can move both before and after the attack, but you must move at least 10 feet before the attack and the total distance that you move cannot be greater than your speed. You cannot use this ability to attack a foe that is adjacent to you at the start of your turn.
Spring attack is its own full-round action. The turn you declare a Spring attack, you cannot declare another Standard action, such as using a Standard action to active a (sp) Domain touch attack. However, you DO make a 'single melee attack' and granted that you have a melee touch attack already active, you can use the touch attack with Spring attack.
Let's look at one example of a touch attack domain power:
Touch of Darkness (Sp): As a melee touch attack, you can cause a creature's vision to be fraught with shadows and darkness. The creature touched treats all other creatures as if they had concealment, suffering a 20% miss chance on all attack rolls. This effect lasts for a number of rounds equal to 1/2 your cleric level (minimum 1). You can use this ability a number of times per day equal to 3 + your Wisdom modifier.
First, note that the ability says (Sp). This means the domain power is a Spell-like ability. It follows many of the rules for spellcasting. Secondly, note that the ability doesn't state whether it takes a Full-round action, standard action, move action, swift action, or free action to use. That means the ability defaults to 'Standard action to use'. Since this power is (Sp), we can follow spell rules, specifically touch spell rules:
Touch Spells in Combat: Many spells have a range of touch. To use these spells, you cast the spell and then touch the subject. In the same round that you cast the spell, you may also touch (or attempt to touch) as a free action. You may take your move before casting the spell, after touching the target, or between casting the spell and touching the target. You can automatically touch one friend or use the spell on yourself, but to touch an opponent, you must succeed on an attack roll.
Touch Attacks: Touching an opponent with a touch spell is considered to be an armed attack and therefore does not provoke attacks of opportunity. The act of casting a spell, however, does provoke an attack of opportunity. Touch attacks come in two types: melee touch attacks and ranged touch attacks. You can score critical hits with either type of attack as long as the spell deals damage. Your opponent's AC against a touch attack does not include any armor bonus, shield bonus, or natural armor bonus. His size modifier, Dexterity modifier, and deflection bonus (if any) all apply normally.
Holding the Charge: If you don't discharge the spell in the round when you cast the spell, you can hold the charge indefinitely. You can continue to make touch attacks round after round. If you touch anything or anyone while holding a charge, even unintentionally, the spell discharges. If you cast another spell, the touch spell dissipates. You can touch one friend as a standard action or up to six friends as a full-round action. Alternatively, you may make a normal unarmed attack (or an attack with a natural weapon) while holding a charge. In this case, you aren't considered armed and you provoke attacks of opportunity as normal for the attack. If your unarmed attack or natural weapon attack normally doesn't provoke attacks of opportunity, neither does this attack. If the attack hits, you deal normal damage for your unarmed attack or natural weapon and the spell discharges. If the attack misses, you are still holding the charge.
Once you activate the domain power as a standard action, in the same round, you can discharge it by attempting to touch your opponent.
But, if you choose NOT to discharge it that round, you are holding the charge, and you effectively have a melee (touch) weapon in your hand. NEXT ROUND, you can spring attack and try to touch your opponent and discharge the spell. If you miss, you are still holding the charge. Here's a flow of how it might look in a game:GM: "There is an orc 15 feet away from Cleric. The orc is doing something irrelevant to combat."
ROUND 1:
Cleric: "I use Touch of Darkness as a Standard action. I end my turn, and I am holding onto the charge."
GM: "Orc does something irrelevant."
ROUND 2:
Cleric: "I declare Spring Attack as a full round action. I move, attack with the Touch of Darkness I've held since last round, and move back. *rolls D20* *misses* I missed, but I'm still holding the charge."
GM: "Okay, now the Orc notices you, and ..."
