为什么在W3C验证器中显示错误的代码“字符数据在这里不允许”

<blockquote>all visible objects, man, are but as pasteboard masks. 
        But in each event -- in the living act, the undoubted

        puts forth the mouldings of its feature from behind 
        the unreasoning mask. If man will strike, strike 
        through the mask. All visible objects, man, are but as pasteboard masks. 
        But in each event -- in the living act, the undoubted 
        deed -- there, some unknown but still reasoning thing 
        puts forth the mouldings of its feature from behind 
        the unreasoning mask. If man will strike, strike 
        through the mask.</blockquote>

Answer 1

blockquote不应该直接包含文本。在验证文本之前，您需要将文本包装在单个p标记或一系列p标记中。

Answer 2

<blockquote>
  <p>My text.</p>
</blockquote>

Answer 3

注意:要将块引用元素验证为严格的HTML/XHTML，元素必须只包含其他块级元素，如下所示：
