+\subsubsection{Multi-sample REF-only blocks}
+When handling VCFs with multiple samples, the length of the $<$*$>$ reference blocks can differ.
+To account for this, a sample-specific END can be specified via the FORMAT END field.
+If any FORMAT END value exists, the INFO END must be present and equal the largest FORMAT END value.
+Positions implicitly called by a preceding $<$*$>$ for a sample must have $GT$/$LGT$ set to the missing value (`.') and have no other FORMAT fields present.
+If $LAA$ is present and a reference block is defined for a given sample, the $<$*$>$ allele must be included as an $LAA$ allele for that sample even though the $LGT$ is $0/0$.

+For example, the genotype-only version of the above example with a second sample with no variants:

-	\item Added local allele support
+	\item Added local allele support (FORMAT LAA, LGT, LAD, LPL) to reduce the size of multi-sample VCFs and enable lossless merging.
