Possible to add multiple 'Collections' to a container

Question

Hello,
In DB XML, is a 'Container' equivalent to an xquery 'Collection' ? All of the examples that I see, refer to the container when specifying the collection.
Basically, I would like to create one Container - call in container1.dbxml Within container1, I would like to have multiple collections, collection1, collection2.
I would then like to be able to run xqueries such as:
count(/*) - and get a count of all the docs in both collection1 and collection2 or
collection("collection1")/* - and get all the nodes in collection1 only
So, bottom line question - can I add multiple collections to a container, or is a container and collection equivalent in DB XML?
Thanks for your responses.

What you want to do is create a class that extends the Java XmlResolver class, and register that class with the XmlManager. In your extended class you would want to implement the following function:
public boolean resolveCollection(XmlTransaction txn, XmlManager mgr, String uri, XmlResults result)
So that the result argument contains all the documents in the collection specified by the uri. You will likely want to do this by querying the container for the documents for the given collection and copying the results returned by the query to the argument.
Below is an example of an implementation of the function that resolves the collection to a single document.
public boolean resolveCollection(XmlTransaction txn, XmlManager mgr, String uri, XmlResults result) throws XmlException {
     XmlDocument doc = mgr.createDocument();
     doc.setName(name);
     doc.setContent(content);
     XmlValue val = new XmlValue(doc);
     result.add(val);
     return true;
