Now we have almost 100% of the transaction variables hosted on the
new schema. Variable modifcators (count and exclusion) are not yet
supported on the new schema. Notice that setvar is now using the
parser.
There is no need for the variable purely associated with the
transaction (transient) be part of collection that demands
lookups. Also, those variables will held the concept of offset:
The offset from the first byte of the request till the start of
the variable.
