Model check, Identifier uniqueness | Sybase XML manual

XML Model objects verified by Check Model

Model check

This check only applies to models built on a schema.

During a model check, the following object controls are made.

Identifier uniqueness

Two or more objects cannot have the same identifier (ID).

Manual correction	Automatic correction
Give a unique identifier to each object	—

Undefined identifier

You must define an identifier (ID) for each object in the model.

Manual correction	Automatic correction
Define an identifier for each object	—

Shortcut code uniqueness

Two shortcuts with the same code cannot be in the same namespace.

Manual correction	Automatic correction
Change the code of one of the shortcuts	—

Undefined target namespace

You should define a target namespace to your model.

Manual correction	Automatic correction
Type a URI for the Target Namespace	—
property in the Detail page of the model
property sheet
