Description
I want to use like this:
New protocol SL
u16 password 0x0102
u8 functionCode
new binary container payloadLen
bin 4 direction
bin 12 length
end binary container
u8 payloadBeginTag 0x02
pdu payloadLen.length + 3
End protocol
but error 'Length field payloadLen.length unknown', How can I use bin container's field as pdu length during define protocol?

Research direction
Start by reproducing the protocol definition from the issue and tracing the validation that reports “Length field payloadLen.length unknown.” Determine how binary-container fields are represented when the PDU length is resolved. Done means the shown definition can use payloadLen.length + 3 without that unknown-field error, with coverage for the resulting length.
