[TYPO3] Image caption using RTE

[Tapio Markula]

Hi


		'imagecaption' => Array (
			'label' => 'LLL:EXT:lang/locallang_general.php:LGL.caption',
			'config' => Array (
				'type' => 'text',
				'cols' => '30',
				'rows' => '3',
				'softref' => 'typolink_tag,images,email[subst],url'
			)
		),


I like to redefine imagecaption to use RTE like 'bodytext'

It has

		'bodytext' => Array (
			'l10n_mode' => 'prefixLangTitle',
			'l10n_cat' => 'text',
			'label' => 'LLL:EXT:lang/locallang_general.php:LGL.text',
			'config' => Array (
				'type' => 'text',
				'cols' => '48',
				'rows' => '5',
				'wizards' => Array(
					'_PADDING' => 4,
					'RTE' => Array(...

but I don't figure how it has been set using RTE
