以下是一篇XML教程中的几段话
1、Unlimited Metadata Support
The style sheet traverses our tree.xml file and uses the generate-id() method to assign a unique ID to each individual entity.
We should note that if this were an n-tier application and our entities were being pulled out of a database, we would not need this process because each entity representing a row in our database would already have a unique identity field.
You'll notice the difference between the two is the customer-specific metadata, such as contact, address, and phone. My folder tree will automatically read and interpret this new metadata.
With the current folder tree architecture, child entities inherit from their parents. For instance, when you right-click on the Customer Folder and select Insert, you will get a child with all the metadata that the Customer Folder has.
2、The exceptions are an insert form initializing blank, meaning with empty input elements, and an update form initializing with values.
3、We also set the focus to this element, which moves the cursor to the begin
ning of the name. After setting several events that restrict keystrokes and allow selecting of text, the user is ready to rename the entity.
