Hi Mike, My apologies. Your syntax DID fix the problem. I was mistaken in assuming that the attribute had to be constructed inside the option tag.

However, this also fails. I will try writing a function to create the option element - that's worth a try!

You could also write a function to create the option element with or without the attribute, but I think the computed constructor is cleaner. -- Mike Tim Meagher wrote: > I am trying to programmatically embed the "selected" attribute in a select > list using xquery but am running into problems.
