The eclipes WTP project provides support for using an XML Catalog based on the OASIS XML Catalog specification. An XML Catalog provides a user with some limited control over how references to other resources handled. So for example if a user has one or more XML documents that reference a DTD or XML Schema via a web address (e.g. http://www.example.org/foo.xsd) they can use the XML Catalog to map this address to their own local copy of this resource. This way 'catalog aware' tools won't need to go off to the internet to fetch the resource. There's several other ways an XML Catalog can be used as defined by the OASIS XML Catalog specification. If you're an eclipse plugin developer there's also some convenient extension points you can utilize to contribute to the XML Catalog settings.
Editing the XML Catalog Settings
TODO...
The XML Catalog can be accessed through the preferences as follows...
1. Select “Window -> Preferences” to launch the Preferences dialog.
2. Expand the “Web and XML” heading and select “XML Catalog”.

TODO.. by Namespace Name by Schema Location
FAQ
TODO...
- I've registered a DTD with a 'System ID' key of 'foo.dtd' and it doesn't work. Why not?
- I've registered an XML Schema with a 'Schema Location' key of 'foo.dtd' and it doesn't work. Why not?
- I've registered my DTD or XML Schema but eclipse is still going off to the internet to fetch a resource. Why?
- I've registered an XML Schema by namespace but XML files are still using the 'xsi:schemaLocation' value. Why?
- Can I register multiple XML Schemas for the same namespace?
No you can't. There should be only one XML Schema registered for a given namespace.
