+<p>This package contains classes for working with content models. In this implementation, the
+standardized content model is pre-processed by <code>transformer</code> into an instance of
+<code>node</code>. Node holds a single element of the content model with the optional unary operation.
+The derived class <code>list</code> holds multiple nodes connected by the same binary operation.
+As the members of this <code>list</code> can also be lists itself, these structures support
+the most of required operations. Several cases when the model cannot be expressed using
+BNF syntax are handled providing specialised classes that are also derived from <code>node</code>.
