How about something like the following:
Code:
<?xml version="1.0"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Mystery of a Hansom Cab</title>
</head>
<body>
<div>
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" height="738" preserveAspectRatio="xMidYMid meet" version="1.1" viewBox="0 0 470 738" width="470">
<image height="738" width="470" xlink:href="../Images/hansom-cab.jpg"></image>
</svg>
</div>
</body>
</html>
Note: the small x in "xMidYMid" is not a typo.
