TSQL inner select value in Outer Where Clause - sql

Question

I have a query that I slimmed down to a very basic example of what I am trying to do.
My issue is that I am creating a dynamic WHERE clause on my tool but can't even get the simple select below to work.
I have a table called BS_TrainingEvent_Segments that contains training events. An event can have multiple segments. My outer Where clause needs to be able to query both the Inner and Outer select but at the point it's at, it just says B cannot be bound.
SELECT A.[teSegmentID],
A.[trainingEventID],
A.[segmentDate],
A.[nonProdHrs],
(
SELECT B.[recordID],
B.[segmentID],
B.[localeID],
B.[teammateCount],
B.[leaderCount]
FROM dbo.BS_TrainingEvent_SegmentDetails AS B
WHERE A.teSegmentID = segmentID
FOR XML PATH ('detail'), TYPE, ELEMENTS, ROOT ('details')
) AS B
FROM [red].[dbo].[BS_TrainingEvent_Segments] AS A
WHERE A.[teCategory] = 'Food' AND B.[localeID] = '462'
FOR XML PATH ('data'), TYPE, ELEMENTS, ROOT ('root')
