```
public class XML11Char
extends java.lang.Object
```
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.
A series of convenience methods are supplied to ease the burden of the developer. Using the character as an index into the XML11CHARS array and applying the appropriate mask flag (e.g. MASK_VALID), yields the same results as calling the convenience methods. There is one exception: check the comments for the isValid method for details.

public XML11Char()
```
- Method Detail
  - isXML11Space
```
public static boolean isXML11Space(int c)
```
    Returns true if the specified character is a space character as amdended in the XML 1.1 specification.
    
    Parameters:
    
    c - The character to check.
  - isXML11Valid
```
public static boolean isXML11Valid(int c)
```
    Returns true if the specified character is valid. This method also checks the surrogate character range from 0x10000 to 0x10FFFF.
    If the program chooses to apply the mask directly to the XML11CHARS array, then they are responsible for checking the surrogate character range.
    
    Parameters:
    
    c - The character to check.
  - isXML11Invalid
```
public static boolean isXML11Invalid(int c)
```
    Returns true if the specified character is invalid.
    
    Parameters:
    
    c - The character to check.
  - isXML11ValidLiteral
```
public static boolean isXML11ValidLiteral(int c)
```
    Returns true if the specified character is valid and permitted outside of a character reference. That is, this method will return false for the same set as isXML11Valid, except it also reports false for "control characters".
    
    Parameters:
    
    c - The character to check.
  - isXML11Content
```
public static boolean isXML11Content(int c)
```
    Returns true if the specified character can be considered content in an external parsed entity.
    
    Parameters:
    
    c - The character to check.
  - isXML11InternalEntityContent
```
public static boolean isXML11InternalEntityContent(int c)
```
    Returns true if the specified character can be considered content in an internal parsed entity.
    
    Parameters:
    
    c - The character to check.
  - isXML11NameStart
```
public static boolean isXML11NameStart(int c)
```
    Returns true if the specified character is a valid name start character as defined by production [4] in the XML 1.1 specification.
    
    Parameters:
    
    c - The character to check.
  - isXML11Name
```
public static boolean isXML11Name(int c)
```
    Returns true if the specified character is a valid name character as defined by production [4a] in the XML 1.1 specification.
    
    Parameters:
    
    c - The character to check.
  - isXML11NCNameStart
```
public static boolean isXML11NCNameStart(int c)
```
    Returns true if the specified character is a valid NCName start character as defined by production [4] in Namespaces in XML 1.1 recommendation.
    
    Parameters:
    
    c - The character to check.

  - isXML11NameHighSurrogate
```
public static boolean isXML11NameHighSurrogate(int c)
```
    Returns whether the given character is a valid high surrogate for a name character. This includes all high surrogates for characters [0x10000-0xEFFFF]. In other words everything excluding planes 15 and 16.

    c - The character to check.
  - isXML11ValidName

    Parameters:
    
    ncName - string to check
    
    Returns:
    
    true if name is a valid NCName
  - isXML11ValidNmtoken
```
public static boolean isXML11ValidNmtoken(java.lang.String nmtoken)
```
    Check to see if a string is a valid Nmtoken according to [7] in the XML 1.1 Recommendation
    
    Parameters:
    
    nmtoken - string to check
    
    Returns:
    
    true if nmtoken is a valid Nmtoken
