Let us assume that we are working w/ Solr xml interface as the datasource
the url may contain start=x&rows=y. assume that we have 100's of rows
to be fetched and we wish to chunk it.

you can change the variable 'start' on each xml fetched (it does not
hurt even if it is set for each row) and you can compute find $hasMore
from the xml itself.

Setting a variable can be done by putting it into the returned row
from a transformer.
