- .. warning::
-
- Check for default value existence is not performed in
- ``evgen_mode``, because previously decoded values are not stored
- in memory, to be able to compare them.
+ All values with DEFAULT specified are decoded atomically in
+ :ref:`evgen mode <evgen_mode>`. If DEFAULT value is some kind of
+ SEQUENCE, then it will be yielded as a single element, not
+ disassembled. That is required for DEFAULT existence check.
