Element Content Model的意思|示意

Examplotron figures out the content model for the element from the first one, and the second one is purely a marker to indicate that it can occur more than once, so you can leave it empty.

Examplotron通过第一个label元素，确定了该元素的内容模型，第二个label元素只是一个标记符，表明它可以出现多次，因此可以让它空着。

The element cannot contain child element. Content model is empty.

元素不能包含子元素。内容模型为空。

The content model should allow for the possibility that the element entity might expand to a list.

内容模型应该允许元素实体可以扩展成列表的可能性。

In this model, element types with attributes, element content, or mixed content (complex element types) are mapped to classes.

在这个模型中，元素及其类型、元素内容或混合内容(复合元素类型)通常被视为类。

Now you'll see how to customize the look, feel, and content of a model element (in this case, to modify the generated output for UML Attribute elements).

现在你将看到如何定制一个模型元件的外形、感觉和内容(本例中，修改为uml Attribute元件生成的输出)。

When you include the XForms schema, you extend the definition of the complex type that defines the content model for the select element — specifically, the type selectType, shown in Listing 3.

包括XForms模式时，扩展了为select元素定义内容模型的复杂类型的定义，即selecttype类型，如清单3所示。
