90 * <p>
91 * This code consists of two main portions. The {@link #compose(XSSimpleType)} method
92 * and {@link #composer} forms an outer cycle, which gradually ascends the type
93 * inheritance chain until it finds the suitable binding. When it does this
94 * {@link #initiatingType} is set to the type which started binding, so that we can refer
95 * to the actual constraint facets and such that are applicable on the type.
96 *
97 * <p>
98 * For each intermediate type in the chain, the {@link #find(XSSimpleType)} method
99 * is used to find the binding on that type, sine the outer loop is doing the ascending,
100 * this method only sees if the current type has some binding available.
101 *
102 * <p>
103 * There is at least one ugly code that you need to aware of
104 * when you are modifying the code. See the documentation
105 * about <a href="package.html#stref_cust">
106 * "simple type customization at the point of reference."</a>
