分享构建XML模型时，是优先将数据作为节点还是优先作为属性？？
例如
1.优先考虑成节点
<method>
<name>tan</name>
<parameters>
<parmeter>
<type/>
<name>number</name>
</parmeter>
</parameters>
<description>Returns the tangent of a number.</description>
<access>public</access>
</method>
2.优先考虑成属性
<method name="tan" access="public">
<parameters>
<parmeter type="" name="number"></parmeter>
</parameters>
<description>Returns the tangent of a number.</description>
</method>

here are some guidelines:
if an entity has a structure, you have to model it as an Element node
if an entity is atomic and has no future potential to contain other information, model it as an Attribute node
if an entity is metadata and atomic, model it as an Attribute model
otherwise, model it as an Element node

是作为节点还是作为属性有一个原则:
属性在大多时候很像数据库中的"主键",如果你不是为了查找那个节点的话,最好把它设为节点.

数据优先以节点形式存放，检索速度快，节点是按ID检索的，属性是按名称检索的，建议最好少用属性，速度慢！
