The Eclipse XML Catalog is used to source XML schemas locally without having to reach out to the http address of the original schema location. This introduces issues for users that are behind a firewall or disconnected from the internet. Existing plugins, such as Spring IDE, automatically populate the catalog with their own schemas. It would be good if IvyDE could do the same, both for the schema associated to the ivy.xml file as well as any schema associated to the ivy-settings file.
