Something that was drawn is no longer drawn
HV-1203 appeared on an earlier revision of this document and not on the current one. Anything still citing the earlier revision is citing an item that has been removed. A register built from a document without asking which revision drew each tag carries deleted items forward, and that is the most common way a deleted valve survives into a commissioning scope.
