[Data-modeling] Cross referencing data within CVTs?

[Ed Laurent]

I'm interested in cross referencing data within CVTs. Is this possible,
pehaps through the use of delegated properties? For example, I want to
create a list of taxa that are designated as priorities within locations as
specified in a written work (i.e., "priority taxa"&"priority location" as a
property of "priority source") and cross reference it with lists on the taxa
and location types (i.e., "priority taxa"&"priority source" as a property of
"priority location", and "priority location"&"priority source" as a property
of "priority taxa") so that all three lists are populated when any one of
them is filled in. I can't figure out how to do this. Is it possible?
