<p>According to <code>RFC 3261</code>:</p>

<blockquote>
<p>qvalue         =  ( "0" [ "." 0<em>3DIGIT ] )<br>
                        / ( "1" [ "." 0</em>3("0") ] )</p>
</blockquote>

<p>This means that <code>1.</code> and <code>0.</code> qvalues MUST be supported. This PR corrects this problem.</p>
