In the Management tab, you can work with existing schemas. Schemas are listed according to type: Page Types, Component Types, and Invalid Schemas.

The number on each tab indicates the total number of schemas of that type.

Page and component schemas are laid out in identically structured tables with columns sorted alphabetically. To sort by a column, click the header (Name, Root Element, etc.). To reverse the order, click the heading a second time.

Clicking New opens the New Schema form, which you can also reach by clicking the Create/Edit tab. When you select a schema from either the page or component table, additional options become available in the Actions menu. Clicking New, Edit, or Clone opens the Create/Edit tab. Clicking Sync opens the Synchronization tab.

To delete a schema, select it, click Delete and click OK in the dialog that opens. If there are pages associated with a schema, it can't be deleted.

Schemas can contain errors. There are two types of schema error: salvageable and unsalvageable. If a page schema refers to a style sheet that doesn't exist, that's a salvageable error. A schema with a salvageable error still appears in the Page Types table, but it's marked with a red warning icon.

A schema that doesn't validate as XML (or doesn't validate as an XML schema) is said to contain an unsalvageable error. Unsalvageable errors can also be caused by duplication of another schema's friendly name or root name.

Schemas with unsalvageable errors appear on the Invalid Schemas tab, with the cause of the error listed in the Error column.

When you select an invalid schema, the Delete command becomes available in the Actions menu.
