Property

 

Description

 

 

 

 

 

 

 

 

Reference

 

Name of an attribute in the current model or another model

 

 

 

opened in the workspace. A reference allows you to reuse an

 

 

 

attribute with all its properties without having to define it

 

 

 

again. Use the dropdown listbox to select an attribute in the

 

 

 

current model. Use the Browse tool to select an attribute from

 

 

 

any model opened in the workspace. If you select an attribute

 

 

 

from another model, a shortcut is created with the referencing

 

 

 

attribute. When you define a reference, name and code

 

 

 

properties are grayed. The name and code are those of the

 

 

 

target attribute

 

Type

 

Attribute data type. It must be a qualified name (See

 

 

 

Glossary). Use the dropdown listbox to select a built-in data

 

 

 

type. Use the Browse tool to select a simple type defined in

 

 

 

the current model or another model opened in the workspace

 

Embedded Type

 

If selected, the attribute data type disappears and a <simple

 

 

 

type> tag is created in the schema within the <attribute> tag.

 

 

 

Only available in a model targeted with XSD

 

Derivation

 

Derivation method for the attribute data type. Used to extend

 

 

 

or restrict the values of the attribute data type. When you

 

 

 

define a derivation, the data type disappears. You must click

 

 

 

Apply and then the Properties tool to select a type, a base

 

 

 

type or member types for the corresponding derivation (list,

 

 

 

restriction or union). Only available in a model targeted with

 

 

 

XSD
