19.7 XML

The XML preferences lets you specify how Designer should handle editing and creation of an XML catalog and XML files. This an Eclipse option; for more details, see the Eclipse documentation.

19.7.1 XML Catalog

The XML Catalog preferences allow you to manage the WST XML catalog implementation. You can add, edit, or delete user-specified catalogs. You cannot use this preference to manage the plug-in specified entries.The XML editor uses the WST XML catalog implementation to resolve XML schema and DTD references for associating URLs, system, and public identifiers with URLs.

Fill in the fields as follows:

Field	Description
Location	Specify a location on disk or a URL of the schema or DTD. Use the Search icon to search Designer’s workspace or the file system.
