(making balanced 2 columns)

They both flag errors when trying to test to see if they work at all.
I get the following error message when I run the following stuff in
XMLSpy 

This file is not well-formed: & expected. Save anyway. 

And it points to the location where the <= operator is present below in
the XSL.

Of course when I execute it flags Xpath errors in XMLSpy as well as
MSXSL 4.0

What seems to be the mistake in this example.
