how to handle option tag when using CGIDEV2 to create xml data

["Lim Hock-Chai" <Lim.Hock-Chai@xxxxxxxxxxxxxxx>]

How does one normally handle optional xml tag when using CGIDEV2 to
create the xml data?
 
should I do something like below?
 
Template:
/$myXMLSec
  <Order> 
   /%myOptTag%/
  </Order> 



RPG code:
updHtmlVar('myOptTag' :'<MyOptTag>blah blah blah</MyOptTag>'); 
wrtSection('myXMLSec');




Or is there a better way of handling this?

thanks
