Examples of org.apache.hivemind.schema.Schema

org.apache.hivemind.schema.Schema
An object which may contain a model, used to identify the form of XML content allowed within some other, containing element.
This is very much provisional; in the future will be more control for validation (i.e, controlling the number of occurances), and support for analogs of W3C SChema sequence and choice. The excess flexibility here forces some validation into element objects (the objects created from the {@link org.apache.hivemind.schema.Rule}s within the {@link org.apache.hivemind.schema.ElementModel}s). @author Howard Lewis Ship
