XML
In addition to syntax errors, XML and XML Schema validation errors can now be highlighted while you are editing. While editing XML or XML schema source, common validation errors are marked with underlining red "squiggles" so errors can be quickly spotted and corrected. This feature can be toggled through the preferences. Window -> Preferences -> General -> Editors -> Structured Text Editors -> Analyze annotations while typing.
XSD
The initial refactoring support is available from source, outline and graph views and provided to:
Make anonymous types global
Make local elements global
Rename components
Refactoring updates are applied automatically; the ability to preview the changes before applying them is planned for a future milestone.
An element's simple type or anonymous (local) simple type can be
selected from the graph view. You can then modify the properties of
the type in the properties view.
The type of an element can now be changed directly from a context
menu. Users can choose to create a new Complex or Simple type for the
element or choose one from among the known existing types.
The multiplicity of an element or content model may be chosen
directly from a context menu. Specify values for minOccurs and/or
maxOccurs may be set from the Properties view. 
The schemaLocation property of an include, import, or redefine is
editable.
