This is a simple set of documents, like a Java set.
You can put documents in it, duplicates are eliminated.
A main usecase is traversing the documents using a
DocumentVisitor.

More interesting is the OrderedDocumentSet. It orders the
contained documents using the site manager's depenence relation.
This way, you can for instance traverse a subtree in preorder
or postorder.

This is a document which contains a list to other documents.

This collection provides XLink attributes for all contained
documens. It is very useful in combination with the XLinkTransformer,
for instance to present a list of titles and summaries of the
contained documents.

Whenever you want :)
