Subject: Re: Proposal to modify Classifications in ebRIM
>To go the other direction it works as well. One can issue a GetClassificationTreeRequest and give it ClassificationNode reference to any node in any scheme, and a integer depth parameter as input. The resulting GetClassificationTreeResponse will have the complete linked tree for the requested sub-tree in the scheme scheme as a single XML document when the depth specified is negative. Othewise it return descendent nodes upto specified level of depth. If the specified node is a root of a scheme then the entire scheme can be retrieved as well. >Does that meet the first use case as you envision it? Yes > > getPath only returns a single node. Note that I set "set of nodes".

I was thinking more along the lines of Europe[5,15] to select a specific set of nodes, such as those forming the EU. Martin
