Scans the specified parameters and executes the callback for every element in the tree. This includes nested content!
the params to scan
the library name
a function that is executed for every element in the semantic structure. Return true in it to abort the scan for the element itself and all of its children (the rest of the scan will continue).
Scans the content parameters (= content.json) of a piece of content and calls a callback for each element in the semantic tree. This includes all nested pieces of content.
You must pass ins a callback that is called for every element in the params tree. If this callback returns true, the scan will be aborted for the element and its children, but not for the rest of the params.
