<TradeplaceMessage xmlns="http://xml.tradeplace.com/schemas/TradeXML/1.0.0/TradeXML.dtd" productionMode="test">

Please note that Tradeplace version (here 2.0.0) might change according to current running version. productionMode can be test or production.
We know that messages without DOCTYPE or xmlns could be send on our former TMH system.
We have improved a lot our new system aka TMH2 and improved verification against our standard protocol. Such controls are raising errors on messages that were accepted on TMH.
