Haha therebs a chunk in the XSLT 3 course i give about streaming and
avoiding this sort of problem.

In streaming mode you can only go down. If you do go up, you can only
look at properties of the ancestors such as name(), not at their
children.

One way to do what you want might be to process record elements. Use a
parameter to store a copy of the primary record. Then when you see a
record,
if it's primary, process the copy of the stored one along with any
secondary records also stored in the parameter.

if it's secondary, add it to the parameter after the stored primary one
(for the next iteration).

that way if there are several secondary records, you'll get copies of
them all in the parameter along with their primary record.

at the end of the iteration process the parameter.

Use the copy-of() function to copy the current record, then look inside
to determine its type, because the copy will be "grounded" - outside
the stream.

Remember also you can call templates in a non-streaming mode, if you
pass them only "grounded" data.
