Can a slowed or staggered character take a 5-ft step?

Both Slow spell and staggered condition restrict characters to a single standard or move action per round.

Pathfinder seems more precise, explicitly adding to staggered condition (which is, in Pathfinder, the effect of the Slow spell) that you can take free, swift and immediate actions.

Meanwhile, 5-ft step is a miscellaneous action. Is it allowed, by RAW, to make a standard action and a 5-ft step (provided that half speed is greater than 5ft) when slowed?
