//Using purely DOM methods as proposed by W3C to simulate .innerHTML  is a little
//tricky, and alludes even a lot of seasoned DHTML programmers. Nevertheless,
//it's doable.
//The following elegant code is devised by Rey Nunez, a surfer of JavaScript Kit 
//and active helper in the JK Forum. Using the below function, we can accomplish 
//dynamic content in NS 6 using DOM methods:

function dynamiccontentNS6(elementid,content){
