/**
* Encapsulates the default handling for leaf classes (which are bound
* to text in XML.) In particular this class knows how to convert
* the lexical value into the Java class according to this default rule.
*
*
* This represents the spec-defined default handling for the Java
* type ({@link #getType()}.
*
*
* For those Java classes (such as {@link String} or {@link Boolean})
* where the spec designates a specific default handling, there are
* constants in this class (such as {@link #STRING} or {@link #BOOLEAN}.)
*
*
* The generated type-safe enum classes are also a leaf class,
* and as such there are {@link CEnumLeafInfo} that represents it
* as {@link CBuiltinLeafInfo}.
*
*
* This class represents the default handling, and therefore
* we can only have one instance per one {@link NType}. Handling of
* other XML Schema types (such as xs:token) are represented as
* a general {@link TypeUse} objects.
