Can a creature lacking a special ability to make either touch attacks or ranged touch attacks nonetheless make against his foes—without provoking attacks of opportunity—touch attacks or ranged touch attacks, respectively, that deal no damage?

That is, while touch attacks and ranged touch attacks in Pathfinder and D&D 3.5 are typically made with spells and special abilities, can any creature make them (dealing no damage and without provoking attacks of opportunity) instead of making one or more standard attacks?

Examples

• Can Two-fisted Abe, street fighter extraordinaire,¹ instead of making a standard attack with his unarmed strike against his foe, make against his foe a touch attack with his unarmed strike that deals no damage, perhaps in an effort to confuse or to bluff his foe or to demonstrate his own confidence?
• Can One-shot Bill, archer against evil,² instead of making a standard ranged attack with his bow, make against his foe a ranged touch attack with his bow that deals no damage, perhaps in an effort to draw aggro from an otherwise engaged foe or reveal his position to particular foe?

While related to this Pathfinder questionquestion on delivering contact poison, given their relationship, I'd appreciate answers address both systems.

¹ He punches streets a lot. He's winning.
² He braces against signs reading evil.
