  We prove that for any semi-Dirichlet form $(\epsilon, D(\epsilon))$ on a
measurable Lusin space $E$ there exists a Lusin topology with the given
$\sigma$-algebra as the Borel $\sigma$-algebra so that $(\epsilon,
D(\epsilon))$ becomes quasi-regular. However one has to enlarge $E$ by a zero
set. More generally a corresponding result for arbitrary $L^p$-resolvents is
proven.
