I'm well aware of the W3C and its validators - I was simply wanting to
know if you were trying to validate the original view script markup or
the rendered markup, as it makes a difference. :P
I've known people to attempt to validate their view scripts in the
past; if you use short tags, validation will fail, but normal tags work
fine. Since you were using short tags, there was a possibility that the
validation error was from an attempt to validate the view script markup,
and not the final, rendered result.
