(刚刚接触,不一定对.)

问题：1. xml model

xml data model用于将数据分组，以方便交互。xml data model对于forms global page, 是可选的。

通常，model在form的最开头。格式如下：

<globalpage sid="global">

 <global sid="global">

 <xmlmodel xmlns:xforms="http://www.w3.org/2003/xforms">          // xforms is the namespace, the url is an          identtity, not visit that url truly.  xmlns is for namespace declare.
