  We obtain new partial H\"older continuity results for solutions to divergence
form elliptic systems with discontinuous coefficients, obeying $p(x)$-type
nonstandard growth conditions. By an application of the method of
$\mathcal{A}$-harmonic approximation, we are able to allow for both
VMO-discontinuities in the coefficients, and the minimal $\log$-H\"older
regularity assumption on the exponent function. In doing so, we recover a local
version of the quantisation phenomenon characteristic continuous coefficient
case.
