\label{Creating_Online_Problems} If you're following this as a tutorial, create one of each of these problem types now. We'll be using them later as raw material to assemble maps and sequences. While several problem types are listed here, in LON-CAPA all problems are actually the same. All problems are written in XML, which can be obtained and edited with the \textbf{EditXML} button. The problem types listed in this manual are just templates. As your knowledge advances, you may wish to play with the XML representation directly to see what you can do.
