# Editing XML schema properties

After you create an XML schema, you can edit its various properties, such as its namespace and prefix.

The following instructions were written for the Resource perspective, but they will also work in many other perspectives.

To edit an XML schema's properties, complete the following steps:

1. Create a new XML schema or double-click an existing schema in the Navigator view. It will automatically open in the XML schema editor.
2. In the Outline view, click Directives.
3. In the Properties view, click the General tab.
4. You can change the Prefix associated with the current namespace. Element and attribute names that are associated with this namespace will be prefixed with this value.
5. You can also edit the Target namespace for this schema. A namespace is a URI that provides a unique name to associate with all the elements and type definitions in a schema.
6. Click the Documentation tab if you want to provide any information about this XML schema. The Documentation page is used for human readable material, such as a description.
7. Click the Extensions tab if you want to add application information elements to your annotations of schema components. The Extensions page allows you to specify the schema and add XML content to your annotations.
8. Click the Advanced tab if you want to define the following additional schema attributes:
   - Prefix for elements (elementFormDefault)
   - Prefix for attributes (attributeFormDefault)
   - Block default (blockDefault)
   - Final default (finalDefault)
