* <li> There is not a unique name with the specified criteria
* <li> The binding associated with the name is null or a problem binding
* <li> The binding is not an instance of the specified class
* </ul>
* @param ast the AST to test.
* @param source the source code corresponding to the AST.
* @param section the code fragment to search for in the AST. The first occurrence of
* an identical section is used.
* @param len the length of the specified section to use as a name. This can also be useful
* for distinguishing between template names, and template ids.
* @param clazz an expected class type or interface that the binding should extend/implement
* @return the associated name's binding
