Cookbook exercise

Based on the previous exercise you should create an online cookbook now. Starting from the recipe model, what elements and attributes do you need to create a model of a cookbook?

• In your XML editor create a new XML document: cookbook.xml
• Copy and paste the DTD and XML from your recipe.xml
• Copy and paste the content for two other recipes into your new cookbook.xml
• Extend your DTD model to include additional elements that you think are required for a cookbook
• Add these additional elements to your cookbook XML and validate your XML document
