blockquote标签应该怎样使用?

关于语义化，不是一句两句就能说明白的，而且现在也没有一个官方的很严格的定义。关于<blockquote>没有争议的是：

1.引用一段较长的文字

2.可以使用cite标签或者属性

问题是<blockquote>引用的文字必须使用块级元素将他包含吗？

首先是来自W3C的解释

9.2.2 Quotations: The BLOCKQUOTE and Q elements<!ELEMENT BLOCKQUOTE - - (%block;|SCRIPT)+ -- long quotation --><!ATTLIST BLOCKQUOTE %attrs;
                              -- %coreattrs, %i18n, %events -- cite
       %URI;
          #IMPLIED -- URI for source document or msg -- ><!ELEMENT Q - - (%inline;)*
           -- short inline quotation --><!ATTLIST Q %attrs;
                             -- %coreattrs, %i18n, %events -- cite
        %URI;
          #IMPLIED -- URI for source document or msg -- >

这两个便签指名包含的内容为引用文字. BLOCKQUOTE 用于长文字的引用(block-level content) 而 Q 用于短文字的引用(inline content) 且不允许引用的句子不完整。

这个例子的文字来自 "The Two Towers", 作者 J.R.R. Tolkien, 最为引用文字.<BLOCKQUOTE cite="http://www.mycom.com/tolkien/twotowers.html"><P>They went in single file, running like hounds on a strong scent,and an eager light was in their eyes. Nearly due west the broad swath of the marching Orcs tramped its ugly slot; the sweet grass of Rohan had been bruised and blackened as they passed.</P></BLOCKQUOTE>

这篇文章是应用web标准进行开发，里面提到了关于一些TAGS的语义下面摘录的是<blockquote>

For longer quotations that form one or more paragraphs, the <blockquote> element should be used. CSS can then be used to style the quotation. Note that text is not allowed directly inside a <blockquote> element
