setting attributes from a namespace

Show all headers | View raw

I have a Javascript application where images are being displayed using SVG.  

The following works:

I define the namespace, e.g.:  
   var xmlns = "http://www.w3.org/2000/svg";

I create each element with a reference to the namespace, e.g.:
   var elem = document.createElementNS (xmlns, "path");

And then I assign attributes in this manner:
   elem.setAttributeNS(null, "fill", fillcolor); //fillcolor has been assigned

This all works great.  I wanted to see if my app would execute faster if I replaced the attribute assignment with something like:
   elem.fill = fillcolor;

In other words, perhaps reducing the amount of text that the interpreter has to process, as well as reducing the number of function calls, might speed things up.  But the elements are not drawn. The browser console indicates no syntax errors.  

Must I use setAttributeNS to make use of the SVG specification?
