FOR XML PATH nested query refer to parent variable

I have the following query:
Select BunCode as '@.BunCode', Min(TradingDate) as '@.TradingDate',
(Select ItemQty, TransactionSequenceNumber, GsiCode, RetalItemCode
FROM ods_TransmitFile WHERE BunCode = 1821
FOR XML PATH, TYPE)
FROM ods_TransmitFile
GROUP BY BunCode
ORDER BY BunCode
FOR XML PATH('BunCode'), ROOT('DM')
The query returns the correct structure however I would like the nested
query to refer to the '@.BunCode' of the parent query.
At present the nested results will always be for BunCode 1821. How can
I set ...WHERE BunCode = @.BunCode to equal the BunCode of the current
element?
Hope this makes sense?Maybe by aliasing the tables? NOTE: *Untested*:
Select otf2.BunCode as '@.BunCode', Min(otf2.TradingDate) as '@.TradingDate',
(Select otf1.ItemQty, otf1.TransactionSequenceNumber, otf1.GsiCode,
otf1.RetalItemCode
FROM ods_TransmitFile otf1 WHERE otf1.BunCode = otf2.BunCode
FOR XML PATH, TYPE)
FROM ods_TransmitFile otf2
GROUP BY otf2.BunCode
ORDER BY otf2.BunCode
FOR XML PATH('BunCode'), ROOT('DM')
