[Ndn-interest] Exclude selector

Dear all,

  I have a question on the exclude selector.

  Suppose that a provider has two data objects (/test/A/B, /test/C/D). Now a consumer issues the interest packet with the prefix "/test". Then, the consumer will get "/test/A/B".

  Now the consumer wants to request the next item using the exclude selector.
  The interest would be "/test <exclude=/A/B>". However, the exclude can only specify a single level such as <exclude= A> or <exclude= B> or <exclude= A, B>. Does anybody know how to express two or more levels in exclude? My guess is to use the appendExclude function, but not sure how to use it.
