Ensure that the field names of the stream columns correspond to FIX fields. The order of columns does not have to follow the order of fields in the FIX dictionary.
The names of main streams can be chosen arbitrarily.
Ensure that descendant streams follow a strict naming convention. Since each descendant stream has a parent stream and corresponds to a repeating group, ensure that its name follows this form:
<parent stream name>_<name of the repeating group>
