how about a "%" indicates a percentage from 0 to 100. if the % is 
missing then assume a fraction so:

<progress value="0.4375"></progress>
<progress value="43.75%"></progress>

are the same as far as DOM and scripting are concerned, for both: 
element.value == 0.4375;

<progress value="43.75"></progress>

would render as "100%" as it is greater than 1.0, the maximum fractional
