Comment:

 A property tree node can have both data and children, i.e. a tree can look
 like this:

 {{{
 root:                           <- has only children
   child1: "child 1 data"        <- has both data and children
     child1.1: "child 1.1 data"  <- has only data
     child1.2: "child 1.2 data"  <- has only data
   child2: "child 2 data"        <- has only data
 }}}

 There is no way to represent such a tree as JSON. A JSON node can be an
 object (it has named children), an array (it has unnamed children), or a
 basic data item (string, number, boolean, null). There is no JSON node
 that can have both direct data and children.

 Therefore, the validation function rejects such trees when generating
 JSON.
