SAX2 extension to augment the entity information provided though a Locator. If an implementation supports this extension, the Locator provided in
ContentHandler.setDocumentLocator() will implement this interface, and the http://xml.org/sax/features/use-locator2 feature
flag will have the value true.
This module, both source code and documentation, is in the
Public Domain, and comes with NO WARRANTY.
XMLReader implementations are not required to support this
information, and it is not part of core-only SAX2 distributions.

Returns the version of XML used for the entity. This will
normally be the identifier from the current entity's
<?xml version='...' ...?> declaration,
or be defaulted by the parser.
Returns: Identifier for the XML version being used to interpret
the entity's text, or null if that information is not yet
available in the current parsing state.

public String getXMLVersion ();
Returns the name of the character encoding for the entity.
If the encoding was declared externally (for example, in a MIME
Content-Type header), that will be the name returned. Else if there
was an <?xml ...encoding='...'?> declaration at
the start of the document, that encoding name will be returned.
Otherwise the encoding will been inferred (normally to be UTF-8, or
some UTF-16 variant), and that inferred name will be returned.
When an InputSource is used to provide an entity's character stream, this method returns the encoding provided in that input stream.
Note that some recent W3C specifications require that text
in some encodings be normalized, using Unicode Normalization
Form C, before processing. Such normalization must be performed
by applications, and would normally be triggered based on the
value returned by this method.
Encoding names may be those used by the underlying JVM,
and comparisons should be case-insensitive.
Returns: Name of the character encoding being used to interpret
* the entity's text, or null if this was not provided for a *
character stream passed through an InputSource or is otherwise
not yet available in the current parsing state.
