  For a pair of spaces $X$ and $Y$ such that $Y \subseteq X$, we define the
relative topological complexity of the pair $(X,Y)$ as a new variant of
relative topological complexity. Intuitively, this corresponds to counting the
smallest number of motion planning rules needed for a continuous motion planner
from $X$ to $Y$. We give basic estimates on the invariant, and we connect it to
both Lusternik-Schnirelmann category and topological complexity. In the
process, we compute this invariant for several example spaces including wedges
of spheres, topological groups, and spatial polygon spaces. In addition, we
connect the invariant to the existence of certain types of axial maps.
