Is this valid use of q, blockquote and cite?
<q>Life is what happens when you're busy making other plans</q>
<cite>John Lennon</cite>
or
<blockquote>Life is what happens when you're busy making other plans</blockquote>
<cite>John Lennon</cite>
<q>
The q
element represents some phrasing content quoted from another source.
<p>And then he said <q>I heart HTML5.</q></p>
<cite>
The cite
element represents the title of a work (e.g. a book, a paper, an essay, a poem, a score, a song, a script, a film, a TV show, a game, a sculpture, a painting, a theatre production, a play, an opera, a musical, an exhibition, a legal case report, etc). This can be a work that is being quoted or referenced in detail (i.e. a citation), or it can just be a work that is mentioned in passing.
<p>My favourite book is <cite>Introducing HTML5</cite> by Bruce and Remy.</p>
<blockquote>
The blockquote
element represents a section that is quoted from another source.
Content inside a blockquote must be quoted from another source, whose address, if it has one, may be cited in the cite attribute.
<blockquote>What we have here is a quotation from another source.</blockquote>
