It looks like the schema-aware type checking has assumed a cardinality of exactly-one for the attribute reference, which fails to take into account that the attribute can be absent if EXPAND_ATTRIBUTE_DEFAULTS is set to false.

- Fix Committed on Branch 9.7, 9.8 added
Since the option to expand (or not expand) default and fixed attribute values can be set for an individual instance document (via the ParseOptions object), I think the safest solution is to change the cardinality inference that such attributes will always be present.
Patch committed on the 9.7 and 9.8 branches.
Note: the problem is present in all known previous releases.
