This product provides an XML schema editor for creating, viewing,
and validating XML schemas. XML schemas are a formal specification of element
names that indicates which elements are allowed in an XML file, and in which
combinations.
A schema is functionally equivalent to a DTD, but is written in XML. A
schema also provides extended functionality such as data typing, inheritance,
and presentation rules.
For more information on XML schema, see the following:
Using the XML schema editor, you can:
- Create and delete XML schema components such as complex types, simple
types, elements, attributes, attribute groups, and groups.
- Edit XML schemas.
- Import existing XML schemas for structured viewing.
The XML Schema specification from the W3C Web site is used for validation.
XML schema editor views - Design, Outline, Properties, and
Source
There are four main views you can work with in the XML schema
editor:
- Design - the Design view provides a graphical way to edit your schema
- Outline - the Outline view shows you the main components in your XML schema.
You can use this view to add and remove certain components.
- Properties - the Properties view enables you to edit the properties of
your XML schema components
- Source - the Source view enables you to edit your source code directly

for the schema are available. They are in the bottom right corner:
- Writable or Read Only.
- (Source view only) Smart Insert or Overwrite.
To toggle between these modes, press the Insert button
on your keyboard.
