According to the vale.4 manpage:
vale ports are named vale[bdg:][port] where vale is the prefix
indicating a VALE switch rather than a standard interface, bdg
indicates a specific switch (the colon is a separator), and port
indicates a port within the switch. Bridge and port names are
arbitrary strings, the only constraint being that the full name
must fit within 16 characters.
The manpage is confusing in that the name must be 15 characters plus the
NUL character. Given the other limits, it looks like bdg can be up to 8
characters in practice.
