Definition Nodes

Definition nodes are the elements to define a Report Type. A definition node has the following attributes;

Attribute	Description	Example
`id`	The id of the definition node within it’s report type It is advised to use unique and meaningful id’s (e.g. for easier association of production issues)	`ov_PO003_ytd`
`buildingBlock`	The type of the building block to be produced Read-only property set when adding the node	`PO003`
`children`	A list (array) of children (definition nodes)
`parameters`	The set of parameters values to be applied when evaluating the building block.
`slot`	The slot to be produced into the parent node should produce a `LayoutBB` that selects a layout via the style parameter Word: the slots are defined within the word layout component and referenced by name Online: the number of slots of a style are built-in and the slots are referenced by order	JSON `"slot": "{left}"`
`enabled`	A boolean (`true`/`false`) or expression that defines if a definition node is evaluated when processing the report	JSON `"enabled": "=params.ShowChapterXY"`
`iterateOver`, `iterateInto`	`iterateOver`: the array of values for which this node (and all it’s children) should be produced. No iteration if undefined. `iterateInto`: the name of the parameter that will be set to the current iteration value.	JSON `"buildingBlock": "SectionBB", "iterateOver": [ "de", "en", "fr" ], "iterateInto": "reportLanguage", "parameters": { "mainTitle": { "text": "This is produced for reportLanguage {1}", "args": [ "=params.reportLanguage" ] } }`
