Attribute general properties | Sybase XML manual

Defining elements

Attribute general properties

There are global and local attributes:

♦Global attributes are defined with the Model menu. In a schema, they are directly linked to the <schema> tag (root element). They can be reused for any element in the model through references (See “NUMBER” attribute in the generated schema)

♦Local attributes only apply to the elements in which they are created. They can be defined by reference to a global attribute (See Reference property)

Global and local attributes in XDR files

In a model targeted with the XML-Data Reduced language, local attributes are first declared separately, like global attributes (with the <AttributeType> tag and a name attribute), then within their parent element (with the <attribute> tag and a type attribute).

Extract of an XDR file:

You can derive an attribute data type to extend or restrict its values. (Only with a model targeted with XSD)

To display an attribute property sheet, double-click its name or its icon in the

Browser tree view.

The General page of an attribute property sheet displays the following properties:

	Property	Description
	Name	The name of the item which should be clear and meaningful,
		and should convey the item's purpose to non-technical users
	Code	The technical name of the item used for generating code or
		scripts, which may be abbreviated, and should not generally
		include spaces
	Comment	Descriptive label of the attribute
	Stereotype	Sub-classification used to extend the semantics of an object
		without changing its structure. It can be predefined or user-
		defined
