"[xX] [mM] [1L]"과 일치하는 처리 명령 대상이 허용되지 않습니다.

CakePHP에서 XML을 출력하고 있습니다. 내가 발리에 내 XML을 넣을 때 나는이 오류를 받고 있어요 : 다음 상단에 <?php echo $this->Xml->header(); ?>와 내가 올바른 XML 레이아웃을 사용하고"[xX] [mM] [1L]"과 일치하는 처리 명령 대상이 허용되지 않습니다.

The processing instruction target matching "[xX][mM][lL]" is not allowed.

<?php echo $content_for_layout; ?>

내 결과는 다음과 같습니다
