TI中文支持网利用3.0协议栈的绑定的理解：
1. 您好，我说一下我的理解关于绑定的：就是两个节点要绑定的时候必须先满足两个节点的 bdb_ZclType1Clusters[]和 bdb_ZclType2Clusters[]包含的簇必须完全一样（这就等于查找匹配了）。感觉好像有点牵强。寻找匹配应该是端点的描述符匹配啦。求教一下到底是哪里寻找匹配的？
2.然后在根据bdb_zclFindingBindingEpType（）该函数进行判断谁是target谁是ininitor。在调用bdb_StartCommissioning（BDB_COMMISSIONING_MODE_FINDING_BINDING）就可实现绑定了。这样理解对吗？
3.到底绑定的流程是怎么样的。我看了BDB的规范。但是还是没有看见具体的代码实现在哪里？请Ti的大神帮忙解释一下，这个问题困扰我好多天了。最好有代码来说明，感激不尽了
