Resource lookup will query the current element and will then skip over to the theme dictionaries, rather than walking up the element tree toward the page root, or checking application dictionaries.
资源查找将查询当前元素，然后跳到主题字典，而不是向上遍历元素树直至页面根元素，或检查应用程序字典。
A resource lookup will not query the current element but will skip over to the theme dictionaries, rather than walking up the element tree toward the page root, or checking application dictionaries.

图2显示了EMF树形视图的一个示例，其下文是一个EMF元素属性视图。
As mentioned earlier, the SOAP element in the tree corresponds loosely to the SOAP envelope.
正如前面提到过的，树中的SOAP元素松散地对应于SOAP信封。
When you select an element in the tree view, the properties view is activated and shows the details of what you have selected.
当您选择树形结构中的某个元素时，它会激活属性视图并显示所选项目的详细信息。
Path location — Creates all ancestors on the navigation path to a target element if they don't exist and returns the target element for a modifiable tree.
路径位置——如果不存在，则创建指向目标元素的导航路径上的所有祖先元素，并返回可修改树的目标元素。
The.. means search down the tree for the named element.
意味着从树中搜索命名的元素。
To link a custom element with a pre-set shadow tree, you need to use the new element.

For example, if an element child inherits from element parent, the schema tree for child will include a group for parent that is based on its type.
例如，如果一个子元素继承自父元素，子元素的架构树将包含一个基于其类型的父元素组。
