xsdeclipse provides an eclipse user interface for xsdTransformer xsdTransformer. xsdTransformer transforms XML schemata to other code (e.g. xhml sites containing XForms forms, JavaServer Pages containing jsf forms et al.). The provided xsdeclipse downloads are completely installable and runnable as it is. For only using xsdeclipse you don't need to download xsdTransformer.
XQDT provides support for editing, execution, and debugging of XQuery modules in Eclipse. Our goal is to have seamless integration with the Eclipse platform and the existing XQuery engines with a user experience consistent with both XQuery and Eclipse standards.
