* from collection.

* you only have to report changes that happened only directly in immediate
* descendants. If it's 2, it should also include changes from the nodes
* below the child collections. (grandchildren)
*

* results should be returned at most. If the limit is not specified, it
* should be treated as infinite.
*

* you should throw a Sabre\DAV\Exception\TooMuchMatches() exception.

* return null.
