/**
* VariableResolver that supports UIX objects. This VariableResolver
* supports one named variable: uix, which provides access to UIX objects,
* like registered data objects and root attributes (in templates).
*
* UIVariableResolver also supports implicit objects for any data providers
* that have been registered in the default (empty-string) namespace.
* For example, if a DataObject is available via
*
* RenderingContext.getDataObject("", "foo")
*
* ... then that data object can be accessed in an expression like
* text="${foo.bar}"

* @deprecated This class comes from the old Java 1.2 UIX codebase and should not be used anymore.
