> There are some performance problems in attribute type evaluation:
> 1. The BasicTilesContainer.calculateType method is called for every attribute, even those that have been already preprocessed. Therefore there is a (pretty small) performance problem. Currently is a case of a null check and a String comparison (plus a call, obiously), but in the future it could be more complex.
> 2. The attribute type should be evaluated only once: when the type is a definition or a template, it is evaluated twice.
> 3. The attribute rendering is dependent on its type: this behaviour can be optimized by using a "switch-case" structure.
