133 (*classname*)
134 this is one of two things:
135
136 1. the *item* is also available under its classname, so a *user*
137 node would also be available under the name *user*. This is
138 also an HTMLItem instance.
139 2. if there's no *item* then the current class is available
140 through this name, thus "user/name" and "user/name/menu" will
141 still work - the latter will pull information from the form
142 if it can.
143 *form*
