I am generating custom XML from components using a C# TBB, and on migrating from 5.3 to 2011, I can see the following additional markup in my XML.
<tcdl:ComponentPresentation type="Embedded" componentURI="tcm:10-111" templateURI="tcm:10-1112-32" xmlns:tcdl="http://www.tridion.com/ContentDelivery/5.3/TCDL">
Actually there are some embedded components, what our code do, it execute tridionEngine.RenderComponentPresentation and append the xml. so this node getting added part of final XML. this particular ComponentPresentation node was not there in 5.3.
Is there any option setting which I can set to avoid above tags from appearing?
