/**
 * Class <code>XSAttributeCheck</code> is used to check the validity of attributes
 * appearing in the schema document. It
 * - reports an error for invalid element (invalid namespace, invalid name)
 * - reports an error for invalid attribute (invalid namespace, invalid name)
 * - reports an error for invalid attribute value
 * - return compiled values for attriute values
 * - provide default value for missing optional attributes
 * - provide default value for incorrect attribute values
 *
 * But it's the caller's responsibility to check whether a required attribute
 * is present.
 *
 * Things need revisiting:
 * - Whether to return non-schema attributes/values
 * - Do we need to update NamespaceScope and ErrorReporter when reset()?
 * - Should have the datatype validators return compiled value
 * - use symbol table instead of many hashtables
