### CONTEXT_INSTANCE

    public static final short CONTEXT_INSTANCE

  See Also:
    Constant Field Values

### CONTEXT_XSITYPE

    public static final short CONTEXT_XSITYPE

  Indicate that the parse of the current schema document is triggered by the occurrence of an "xsi:type" attribute, whose value (a QName) has the target namespace of this schema document as its namespace.

  Returns:
    the type of this grammar
  See Also:
