 <p>A list of comma and/or white space separated <a href="/ja/SVG/Content_type#Length" title="en/SVG/Content_type#Length"><var>&lt;length&gt;</var></a>s and <a href="/ja/SVG/Content_type#Percentage" title="en/SVG/Content_type#Percentage"><var>&lt;percentage&gt;</var></a>s that specify the lengths of alternating dashes and gaps.</p>

 <p>If an odd number of values is provided, then the list of values is repeated to yield an even number of values. Thus, <code>5,3,2</code> is equivalent to <code>5,3,2,5,3,2</code>.</p>
