                <h1>Does your browser support SVG <code>lang</code> without the <code>xml</code> prefix?
<p>Green is correct; red and crossed-out is not (except for the last line, which tests that the styles are working correctly).  This version uses regional language codes (Canadian English is good, US English is bad, sorry) because Safari wasn't matching any language codes with custom extensions.</p>
<p>Also, all the text spans should be centered; MS Edge is currently messing up the layout of nested tspans.</p>
<h2>Inline SVG:</h2>
    <tspan x="50%" dy="1.5em" xml:lang="en-ca">
      Basic :lang() support, with prefix</tspan>
