deep copy the entire structure however:
if there is a bignodes whose ccua field contains the string 'cc' do the following
1) if ccua = "cc 1" discard that node
2) else
2a) change bignodes attribute outDX to 2000
2b) for every dcc node whose attribute "value">0 set value=20
2c) eliminate any dcc node whose attribute "value" < 0
point 2b & 2c are the least important
