text: """debugging handling when an attribute is sometimes referrable
  
  Background:
  Previously, some VRS objects had "referrable" attributes, which means
  that they could be either the inline object or a reference.  For
  example, Allele.location could be either an inline Location or a
  CURIE. Things got more complicated when an attribute used oneOf,
  because that required checking whether any of oneOf options was
  identifiable; if so, we assumed that they were all identifiable.
