The description of AlternateBases refers to "symbolic alleles" as being represented in VariantType, and lists a number of those.
IMO this is dangerous since it a) binds the documentation to VCF and b) pre-empts a clear definition of which specific variant types will be served by the protocol.
Proposal: Replace this part with
Categorical variant queries, e.g. such *not* being represented through sequence & position, make use of the `VariantType` parameter.
