# Package com.saxonica.ee.domino

This package is an implementation of a tree structure allowing efficient navigation of DOM trees. The DOM tree is retained in its original form, but fast navigation is provided using an index structure which essentially replicates the structural information used in Saxon's native TinyTree model.

The Domino model is available only in Saxon-EE, where it is used by default when a DOMSource is supplied as the input to a transformation or query.
