您需要通过#{cc.attrs.<name>}引用复合组件属性值，其中<name>是属性名称.因此，应该这样做:
You need to reference composite component attribute values by #{cc.attrs.<name>} where <name> is the attribute name. So, this should do:
<h:inputText value="#{cc.attrs.model.vorname}">
<composite:xxx>标签文档
<composite:xxx> tag documentation 无关与具体问题无关，组合中的所有<html><head><body>都是不必要的.我建议使用<ui:component>，因为这更加清楚.有关示例，请参见我们的复合组件Wiki页面.
Unrelated to the concrete problem, all that <html><head><body> in the composite is unnecessary. I suggest to use <ui:component> since that's more clear. See also our composite component wiki page for examples.
