/**
* Abstract base class for implementations of {@link ElementBuilderBase}.

* a shared implementation that handles the actual building. The wrappers merely
* delegate to the shared implementation, so wrapper instances can be reused,
* avoiding object creation. This approach is necessary so that the return value
* of common methods, such as {@link #id(String)}, return a typed builder
* instead of the generic {@link ElementBuilderBase}.
