why, e.g., input/@checked="checked" ?

Hi,

I generate XHTML/JSP/Velocity pages from XSL and XML. One thing always 
seems clumsy to me: that is, why was something like an INPUT's checked 
attribute be set to "checked" and not true/false?

A source XML that will be generated to a Velocity template, for example, 
would need to look like the following to maintain well-formedness:

#set ($isChecked = $page.getBoolean("isChecked"))

#if ($isChecked)
   <input type="checkbox" value="true" name="something" checked="checked"/>
#else
   <input type="checkbox" value="true" name="something"/>
#end

rather than using true/false on the checked attribute, for example:

<input type="checkbox" value="true" name="something" 
checked="${isChecked}"/>

Don't suppose there is any chance to change this? :)

best,
-Rob
