Given factorizations of two joint densities $p(x_1,...,x_n)=\prod_{i=1}^n p(x_i\mid \textrm{cond}(x_i))$ and $q(x_1,...,x_n)=\prod_{i=1}^n q(x_i\mid \textrm{cond}(x_i))$, where $\textrm{cond}(\bullet)$ denotes the set of conditioning variables, does the KL-divergence decompose, i.e., does
$\textrm{KL}(p\Vert q)= \sum_{i=1}^n \textrm{KL}\left(p(x_i\mid \textrm{cond}(x_i))\ \Vert\ q(x_i\mid \textrm{cond}(x_i))\right)$
hold?
