XTCE13 — Discrete lookup list has no default (or i don't get it)

The discrete lookup list, also sprinkled about the syntax tree retrieves the specified numeric value if its condition evaluates to true. for particular discrete in the list. there are several kinds of conditions. The text isn't completely clear but it seems the first discrete lookup in the list that evaluates to true – returns that value. But what happens if none eval to true? it seems that default value is warrented.

Note: the value is a long. Therefore it does not have same problem as dynamic lookups double data types for integer syntax items.
