Just wondering, is there any real difference between having say a 
<for-each-row query="select whatever from whatever"> macro in JXTG and 
SQL transformer? In fact, wouldn't JXTG be more useful for publishing 
(since you can perform conditional branching and additional variable 
substitution) than SQL Transformer? Or, if not then perhaps SQL 
transformer itself should be eliminated. At any rate, shouldn't it be a 
generator rather than a transformer?
