Block containers in XMLOUT are equivalent to frames in PageOUT. When you drop a block on an element in the Process view, the block is automatically encapsulated in a block container. You can add several blocks to a block container, and you can add blocks to several block containers.
If you add several blocks to one block container, the order in which block data is delivered depends on the order in which data is received – and whether or not sorting is enabled in the Event configuration.
If you add the blocks to several block containers, block data from the first block container will be delivered first, data from the second block container next, and so on.
When you add a block to an element in the Process view, it does not contain anything. You must manually build the structure of elements, static text, etc. within each block. You can do this using shortcut menu commands. You can also drag nodes from a template, or from the surrounding XML structure.
