+/**
+ * The output of the XMLLayout consists of a series of log4j:event
+ * elements as defined in the <a href="log4j.dtd">log4j.dtd</a>. If configured to do so it will
+ * output a complete well-formed XML file. The output is designed to be
+ * included as an <em>external entity</em> in a separate file to form
+ * a correct XML file.
+ * <p/>
+ * <p>For example, if <code>abc</code> is the name of the file where
+ * the XMLLayout ouput goes, then a well-formed XML file would be:
+ * <p/>
+ * <pre>
+ * <?xml version="1.0" ?>
+ *
+ * <!DOCTYPE log4j:eventSet SYSTEM "log4j.dtd" [<!ENTITY data SYSTEM "abc">]>
+ *
+ * <log4j:eventSet version="1.2" xmlns:log4j="http://jakarta.apache.org/log4j/">
+ * &data;
+ * </log4j:eventSet>
+ * </pre>
+ * <p/>
+ * <p>This approach enforces the independence of the XMLLayout and the
+ * appender where it is embedded.
+ * <p/>
+ * <p>The <code>version</code> attribute helps components to correctly
+ * intrepret output generated by XMLLayout. The value of this
+ * attribute should be "1.1" for output generated by log4j versions
+ * prior to log4j 1.2 (final release) and "1.2" for relase 1.2 and
+ * later.
+ * <p/>
+ * Appenders using this layout should have their encoding
+ * set to UTF-8 or UTF-16, otherwise events containing
+ * non ASCII characters could result in corrupted
+ * log files.
