DWV experts: Can I use a sanitary tee to vent a fixture drain?

I understand why sanitary tee's are used in most cases. I would never substitute a vent tee for a sanitary tee, but can I substitute a sanitary tee for a vent tee?

fine print:

Home Depot doesn't even stock vent tee's. By vent tee I mean the ones that are a right angle instead of the swoop.

I am trying to vent a individual fixture drain after the P trap with a plain vertical vent. I would mount the sanitary tee so as not to encourage the waste to ramp up into the vent.

I know the ultimate say is with the code official but I wonder if there's anything in the code that forbids this.

The sanitary tee should be fine. It'll allow outside air to protect the trap water from being sucked out in any conceivable condition, as long as it isn't rediculously undersized.
