forEach="/record | /record/mediaBlock" is likely to have problem .
This causes inconsistencies anyway because this is supposed to give
callbacks with same data.
you can definitely write a transformer which gives out multiple rows
if a record contains /record/mediaBlock. the return value of a
transformer can be a Map<String, Object> or a List<Map<String,
Object>>. In the second case it can create multiple rows for each
incoming row
