> UILeaf is a facelets internal class that acts as a wrapper for html markup.
> Since this is a stateless transient class, used intensively by JSF it is
> better to reduce the size and overhead caused by this class.
> 1. Make this class extends from UIComponent instead UIComponentBase to reduce
> the overall size of the object in memory.
> 2. Do not use an extra object for implement its attribute map.
> 3. Use a variable for ComponentSupport.MARK_CREATED instead store it into a
> HashMap.
> With these optimizations we can reduce object size to less than a half and
> replace a lot of calls to HashMap.get() by simple variable assignments.
