  Simulation studies have been carried out to explore the ability to
discriminate between single-site and multi-site energy depositions in large
scale liquid scintillation detectors. A robust approach has been found that is
predicted to lead to a significant statistical separation for a large variety
of event classes, providing a powerful tool to discriminate against backgrounds
and break important degeneracies in signal extraction. This has particularly
relevant implications for liquid scintillator searches for neutrinoless double
beta decay ($0\nu\beta\beta$) from $^{130}$Te and $^{136}$Xe, where it is
possible for a true $0\nu\beta\beta$ signal to be distinguished from most
radioactive backgrounds (including those from cosmogenic production) as well as
unknown gamma lines from the target isotope.
