* do not perform case normalisation. If you are parsing HTML, you are invited
* to downcase your names before accessing {@link #getElement(MutableString)}
* and {@link #getAttribute(MutableString)}.
*
*
This class is a singleton, and its only instance is accessible using the public field
* {@link #INSTANCE}.
*
*
The relationship between this class and {@link Element}/{@link Attribute} is a bit
* twisted due to the need to accomodate two features:
*
* - (X)HTML interned objects must be accessible directly (see, e.g., {@link Element#A});
*
- (X)HTML interned objects must be put into suitable name-to-object maps.
*
*
* To this purpose, this class exports packagewise some static factory methods that create {@link Element}s and
* {@link Attribute}s and register them locally. The static initialisation code in
* {@link Element} and {@link Attribute} creates elements such as {@link Element#A} using the abovementioned
* factory methods.
*
*
An alternative implementation could use reflection, but I don't see great advantages.
