Project XSQL

I attempted to convert SQL views from our project into XSQL pages. Believe it or not, I was successful on my first five attempts at converting our views. However, I came across some troubles when it came to a few of our queries. I think the source of the problem has to do with making the XSQL page well-formed. In two of our queries we have the not equal to symbol (<>). I remember somewhere hearing or reading that the processes views the < sign as the beginning of a new element or something. There has to be a way to represent <> without using the < sign. If anybody knows the code please blog back. Other than that my XSQL pages worked fine. However, I was a little curious with the id-attribute part of the XSQL page. What is the purpose of the id-attribute function? I had no idea so I left it blank in all the queries I did.
