Couple of Divine Bond (Weapon) questions

[Sorwen]

I have a couple questions about Divine Bound.

1) This doesn't seem to have a duration like the D&D version that I can see. Is that correct?

2) A magical weapon can only be made with a maximum of +10 worth of enhancements. Could this be used to exceed that amount? For instance could an 8th level Paladin have a +5 keen(+1) holy(+2) flaming burst(+2) sword then add disruption(+2) from the bond on top of that? Would it instead supersede one of the abilities or just couldn't be done at all?

Divine Bond (Sp): "The first type of bond allows the paladin to enhance her weapon as a standard action by calling upon the aid of a celestial spirit for 1 minute per paladin level."

Magic Weapons: "A single weapon cannot have a modified bonus (enhancement bonus plus special ability bonus equivalents, including those from character abilities and spells) higher than +10."

1) Thanks. I read over that 1 minute per paladin level half a dozen times or more. Totally blind on that one.

2) Thanks on that too. All I saw was "A weapon's enhancement bonus and special ability bonus equivalents can't total more than +10."
