The treecontainer tag is a the `container' tag for the tree-tag. It searches on the same way as the tree tag itself for a `starting query', the only difference being that it will not itself look for a surrounding tree-container (so, it will look parent node-list-containers and if unsuccessfully for a parent node-providers).
Just as for example in the relatednodescontainer the attributes define how the `starting' query must be extended. The essential difference for `trees' though, is that it will happen recursively. So the surrounding querycontainerreferrer tags like `mm:constraint' will work only on a kind of `template' query, and will then be applied repeatedly.
The use of treecontainer, tree and its subtags can perhaps most easily be explained by an example, which can be find on the page about tree related tags.(since: MMBase-1.7.1)
