/**
* This class defines the basic properties of characters in XML 1.1. The data
* in this class can be used to verify that a character is a valid
* XML 1.1 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. Using the character as an index into the <code>XML11CHARS</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.
