I understand that. I was asking why.

What I am trying to say is that it makes generating XHTML output 
clumsy/redundant because a source XML used in an XSL transformation to a 
templating language for runtime cannot look like (velocity):

<input #if($isChecked)checked="checked"#end/>

or (jsp):

<input <%=if(isChecked)checked="checked";%>/>

I realize it is not the goal of the HTML working to accomodate these 
situations. It just doesn't seem logical to me. I was wondering if there 
was a logical explanation.
