question about Title.php

[typostudy]

<?php
 
/**
* Class to handle compiling template tag calls for "title".
*
* @package XenForo_Template
*/
class XenForo_Template_Compiler_Tag_Title implements XenForo_Template_Compiler_Tag_Interface
{
    /**
    * Compile the specified tag and return PHP code to handle it.
    *
    * @param XenForo_Template_Compiler The invoking compiler
    * @param string                Name of the tag called
    * @param array                  Attributes for the tag (may be empty)
    * @param array                  Nodes (tags/curlies/text) within this tag (may be empty)
    * @param array                  Compilation options
    *
    * @return string
    */
    public function compile(XenForo_Template_Compiler $compiler, $tag, array $attributes, array $children, array $options)
    {
        if (empty($options['allowRawStatements']))
        {
            throw $compiler->getNewCompilerException(new XenForo_Phrase('x_tags_only_used_where_full_statements_allowed', array('tag' => 'title')));
        }
 
        $var = '__extraData[\'title\']';
        $childOutput = $compiler->compileIntoVariable($children, $var, $options, false);
 
        return $compiler->getNewRawStatement($childOutput);
    }
}

Above code is taken from: library\XenForo\Template\Compiler\Tag\Title.php,
I am just thinking how does it work? eg.

<xen:title>Page Title</xen:title>

So is XenForo_Template_Compiler $compiler=xen? $tag=title? $attributes=Page Title?
