* Performs a transformation on a XDOM (i.e. a tree of {@link org.xwiki.rendering.block.Block}. This used for example
* for transforming Macro Blocks into other Blocks corresponding to the execution of the Macros. Another example of
* transformation would be looking for all words that have an entry on Wikipedia and adding links to them.
