Fluid Content Element

Ich geh mal nach Verzeichnissstruktur durch (myext ist der Extensionkey):

myext/ext_tables.php:

<?php
if (!defined('TYPO3_MODE')) {
    die ('Access denied.');
}
t3lib_extMgm::addStaticFile($_EXTKEY, 'Configuration/TypoScript', 'Extensionanme');
?>

--
myext/Configuration/TypoScript/setup.txt:

plugin.tx_fed {
    fce.tx_myext {
        label = Extensionname FCEs
	templateRootPath = EXT:myext/Resources/Private/Elements/
	partialRootPath = EXT:myext/Resources/Private/Partials/
	layoutRootPath = EXT:myext/Resources/Private/Layouts/
    }
}

--
myext/Resources/Private/Layouts/Default.html:

<div class="tx-myext">
	<f:render section="Main" />
</div>
