We need a mechanism to specify children ordering in containers. Currently it is controlled using ORDER BY in the container's SELECT query, and while that works correctly, the ordering is generally lost after we wrap the query into DESCRIBE and retrieve a graph, which is unordered. Therefore a secondary sort in XSLT needs to be done, and to be able to sort by properties and their values, we need to know the URI of the property used as the sort key.
