/**
 * This class defines the basic XML character properties. The data
 * in this class can be used to verify that a character is a valid
 * XML character or if the character is a space, name start, or name
 * character.
 * <p>
 * A series of convenience methods are supplied to ease the burden
 * of the developer. Because inlining the checks can improve per
 * character performance, the tables of character properties are
 * public. Using the character as an index into the <code>CHARS</code>
 * array and applying the appropriate mask flag (e.g.
 * <code>MASK_VALID</code>), yields the same results as calling the
 * convenience methods. There is one exception: check the comments
 * for the <code>isValid</code> method for details.
