it is not only very difficult to search value if anelement (<currency>)
contains both element (<id>) and text value(USD) but alsoreturns false
result.

B B B B B B B B B B B B B B  <amount>
B B B B B B B B B B B B B B B B B  <currency>
B B B B B B B B B B B B B B B B B B B B 
<id>settlementCurrency</id>USD</currency>

<referenceAmount>StandardISDA</referenceAmount>
B B B B B B B B B B B B B B B B B  <cashSettlement>true</cashSettlement>
B B B B B B B B B B B B B B  </amount>

B 

That USD really is the value of <currency>. In this case, it is legitimate
andsensible to transform id as sibling element of its originalelement
<currency> (its parent is still <amount>) to:

B 

<amount>
B B B  <currency>USD</currency>
B B B  <id>settlementCurrency</id>
B B B  <referenceAmount>StandardISDA</referenceAmount>
B B B  <cashSettlement>true</cashSettlement>
</amount>

The flattened XML is very searchable (an index on 'currency' is good enough)
and can be transformed to JSON.

What is the criteria to transform an attribute to a child element of its
parent as is done for the "id" of the "bcs" element and what is the
criteria for the other choice, to not include the new element as a child
but to make it a sibling of the (previous) parent element?
